• Can't install software by terminal

  - by behnam mohammadi

  I don't know what packages i have installed that i no longer can get and install packages in terminal. e.g. when trying to install Prozgui, i got this error: Traceback (most recent call last): File "/usr/bin/add-apt-repository", line 60, in <module> sp = SoftwareProperties() File "/usr/lib/python2.7/dist-packages/softwareproperties/SoftwareProperties.py", line 90, in __init__ self.reload_sourceslist() File "/usr/lib/python2.7/dist-packages/softwareproperties/SoftwareProperties.py", line 538, in reload_sourceslist self.distro.get_sources(self.sourceslist) File "/usr/lib/python2.7/dist-packages/aptsources/distro.py", line 91, in get_sources raise NoDistroTemplateException("Error: could not find a " aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template and it happens for all others too. Plus, my Software Center has been disabled and doesn't start. I get this error for that too: Traceback (most recent call last): File "/usr/bin/software-center", line 111, in <module> from softwarecenter.app import SoftwareCenterApp File "/usr/share/software-center/softwarecenter/app.py", line 40, in <module> from softwarecenter.db.application import Application, DebFileApplication File "/usr/share/software-center/softwarecenter/db/application.py", line 30, in <module> from softwarecenter.distro import get_distro File "/usr/share/software-center/softwarecenter/distro/__init__.py", line 151, in <module> distro_instance=_get_distro() File "/usr/share/software-center/softwarecenter/distro/__init__.py", line 140, in _get_distro module = __import__(distro_id, globals(), locals(), [], -1) ImportError: No module named OPTIMOS Can anyone please help me with this?

• How can I downgrade a system that accidentally had backports installed?

  - by Glyph

  I installed a fresh Ubuntu system. Somehow - possibly through my own error - the backports repository got enabled. Then I did several upgrades. I noticed that this happened when networking suddenly stopped working, "Network Settings" now has an "(alpha)" in the title bar, "System Settings" ? "Network" now displays an error dialog saying "The system network services are not compatible with this version". Now, I've disabled the backports repository, and I'd like to restore my system to its previously-functional state. My question is twofold: How do I determine which packages were installed from backports? Can I automatically re-install all those packages (and purge their configuration) to get back to a sensible state? If the answer to 2 is "no" I can probably manually purge some things and reinstall, but it would be nice to have it handled automatically. Update: It wasn't an update that broke the network; it was apt-get install indicator-network, which installed something called "connman" and removed network-manager and network-manager-gnome. Nevertheless I am leaving the question up, since I am still interested in how I can purge packages from a particular source after accidentally adding that source, and how I can determine which packages were installed from where.

• Unable to remove the lock by normal means

  - by Loki

  I've been installing ubuntu restricted extras via the software center. Everything was going well at first, but then the installation process froze on 'applying changes' stage. I've had this in the past already, and usually just hitting the 'cancel' button helped, but not this time. Obviously, the install process has placed a lock, and I couldn't issue any apt-get commands. then i've tried doing what was suggested here Fixing Could not get lock /var/lib/dpkg/lock : sudo fuser -cuk /var/lib/dpkg/lock; sudo rm -f /var/lib/dpkg/lock but it seemed to me that it has only killed my X server. Okay, i've just pressed the power button on my PC, and restarted, hoping that the lock was finally off and i could reinstall the stuff. No dice. when I open the software center, I still have one operation in process, a weird one: " Searching | Cancelling ". The 'cancel' button is either inactive, or it just does nothing. So I've become desperate and decided to write here. How do I fix the problem? Can't install anything on a fresh ubuntu 12.04 :) Thanks in advance

• Trying to build/install patched gtk3-engines-oxygen to test bugfix, get shared changelog.Debian.gz is different from other instances of package

  - by andlabs

  I want to just quickly test the patch in this bug report to gtk3-engines-oxygen so it can go upstream. I could test it either temporarily or permanently; I would just like to do it. I currently have the package installed. So far, I've tried: $ mkdir /tmp/o # keep everything self-contained $ cd /tmp/o $ apt-get source gtk3-engines-oxygen $ cd oxygen-gtk3-1.3.5/ $ patch -p1 < /path/to/patchfile $ dpkg-source --commit # to make debuild happy (name 'layout'; just save the default; this is a test) $ debuild -us -uc # bypass signature checks $ sudo debi ../oxygen-gtk3_1.3.5-0ubuntu1_amd64.changes According to some people on #ubuntu-packaging, this is what I have to do. It's this last step that's the problem; I'm getting (Reading database ... 503333 files and directories currently installed.) Preparing to unpack gtk3-engines-oxygen_1.3.5-0ubuntu1_amd64.deb ... Unpacking gtk3-engines-oxygen:amd64 (1.3.5-0ubuntu1) over (1.3.5-0ubuntu1) ... dpkg: error processing archive gtk3-engines-oxygen_1.3.5-0ubuntu1_amd64.deb (--install): trying to overwrite shared '/usr/share/doc/gtk3-engines-oxygen/changelog.Debian.gz', which is different from other instances of package gtk3-engines-oxygen:amd64 Errors were encountered while processing: gtk3-engines-oxygen_1.3.5-0ubuntu1_amd64.deb debi: debpkg -i failed What's going on? How do I fix it? Or am I doing this completely wrong (and ergo so are they)? I'm using Kubuntu 14.04 amd64. Thanks.

• Autojump in 12.04 doesn't work

  - by hnasarat

  https://launchpad.net/ubuntu/+source/autojump I installed with apt-get, checked out the man page and added . /usr/share/autojump/autojump.sh to my .bashrc, like it says. When I cd around the filesystem, nothing gets added to ~/.local/share/autojump. I then tried adding . /usr/share/autojump/autojump.bash, but that didn't work either. autojump -a ~/Dropbox properly creates a file ~/.local/share/autojump/autojump.txt, but running j Drop < TAB > doesn't autocomplete to j ~/Dropbox/ as it should. However, j < TAB > does autocomplete to j ~/Dropbox. I know my bash-completion is working since it works for git, dd, and others. I know there's a newer version in the repositories set for Quantal. Perhaps that would work? I don't know how to install that version though. I've used autojump with mac homebrew (and it installed without any issue), so I know there is missing functionality. In general I'm really annoyed that I can't get this working...I've spent hours on it! Needless to say, help would be very appreciated.

• How to fix Ubuntu 12.04.3 boot to black screen full of errors in white text, after upgrading on dell inspiron 1501

  - by Ibuntu

  I am running a Dell Inspiron 1501 I use Linux only. No Microsoft or Apple operating systems (or really anything closed-source). I've only been using Linux for a little over a year but I'm starting to gain a comfortable level of familiarity with the system and terminology. I've been having some issues with Quantel Quetzal and Raring Ringtail, especially with older hardware, so I opted to install Ubuntu 12.04.3 Precise Pangolin on the Inspiron 1501. I checked my MD5 sum after downloading my ISO and all was good. I have in fact used this iso/dvd to install Precise Pangolin successfully on a few other systems (some of which are even older than this laptop). Install goes fine. The wireless card doesn't work out of the box but this is a known issue which is fairly easy to fix. So, first thing I did was open up a terminal and run sudo apt-get update && sudo apt-get upgrade which, part way through, crashed (I assume lightdm and possibly X) and took me to a black screen filled with white lines of text that were either errors or just the ouputs of commands. The reason I say that is because I was unable to gleam any useful information from the output on the screen. I did take a picture however and will post a link. After that, every time I boot the system it goes right to that black screen posting all the error messages or output in white text. I never get a purple Ubuntu splash, so from what I can tell after reading this wiki article: https://wiki.ubuntu.com/X/Troubleshooting/BlankScreen That means that after the kernel is selected, it is unable to correctly implement the settings it needs. If the purple splash never shows, the frame buffer was never set correctly right? This leads me to believe that it could be a kernel issue? The wiki suggested to try and pinpoint the issue by rolling back kernels until I find one that works. Is this my best option? I think I'm going to give it a try anyways and will let everyone know if I am able to solve the issue this way. I have since done a few reinstalls and some trouble-shooting including a couple hours scouring the net for anyone with any kind of similar issue. Most of the issues I could find involved getting a black screen after login and none of them said anything about any information output on this black screen. My reinstalls have taught me that there is no issue updating, but as soon as I run sudo apt-get upgrade my system goes to the black screen and every time I boot it up it does the same thing. The only way to fix is by reinstall. I never get any ability to log in. After a hard power off to the laptop (because I cannot use ctrl+alt+del to reboot) when it boots again it goes to the grub boot menu and I can select between regular boot, recovery mode and the two memtest options. I never tried the memtest options but the other two both lead to the same black screen. Some people having a black/blank screen issue claim to have fixed it by using 12.10 or 13.04 but I believe they were having a different issue where they got a black/blank screen after logging in. I think I will still give these images a try, but mostly figured I would just wait another day or two for 13.10. Other things I figured I would try from the following three articles: After logging in, there's a black screen and my cursor, nothing else! in Ubuntu 12.10 Black Screen on Login After Upgrading to 12.04 I can't get to the login screen include opening a terminal using ctrl+alt+f1 and trying a variety of reseting unity, x settings, lightdm (or switching to gdm); but I doubt this will work or that I will even be able to access a terminal. I'm pretty sure the whole system is stuck after it loads the last line on the black screen. I will try these things and post more information when I have. Hopefully someone has an idea in the meantime and I will keep checking back trying to find a solution. Thank you. Here are 3 different pictures of the error message. I had to take with my phone: http://ubuntuone.com/album/0TBBkxmVajJIQQtoN9mVdN

• Can't upgrade MySQL Server on new Ubuntu 12.04 install

  - by user179627

  After freshly installing Ubuntu server 12.04, I did the usual apt-get update / apt-get upgrade, which failed for mysql-server-5.5: Setting up mysql-server-5.5 (5.5.31-0ubuntu0.12.04.2) ... start: Job failed to start invoke-rc.d: initscript mysql, action "start" failed. dpkg: error processing mysql-server-5.5 (--configure): subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of mysql-server: mysql-server depends on mysql-server-5.5; however: Package mysql-server-5.5 is not configured yet. dpkg: error processing mysql-server (--configure): dependency problems - leaving unconfigured I tried a wide variety a approaches suggested by googling, which involved various combinations of apt-get remove/purge/install -f/reinstall, etc., with no luck. I also tried downloading the package directly from launchpad.net and running dpkg -i on it (this had worked for a similar issue with a kernel upgrade), but to no avail. I'm not actually particularly interested in what's going on with mysql, per se (though I will need to figure it out at some time); at this point, my primary concern is that I am unable to apt-get install other packages! What to do?

• Beware: Upgrade to ASP.NET MVC 2.0 with care if you use AntiForgeryToken

  - by James Crowley

  If you're thinking of upgrading to MVC 2.0, and you take advantage of the AntiForgeryToken support then be careful - you can easily kick out all active visitors after the upgrade until they restart their browser. Why's this?For the anti forgery validation to take place, ASP.NET MVC uses a session cookie called "__RequestVerificationToken_Lw__". This gets checked for and de-serialized on any page where there is an AntiForgeryToken() call. However, the format of this validation cookie has apparently changed between MVC 1.0 and MVC 2.0. What this means is that when you make to switch on your production server to MVC 2.0, suddenly all your visitors session cookies are invalid, resulting in calls to AntiForgeryToken() throwing exceptions (even on a standard GET request) when de-serializing it: [InvalidCastException: Unable to cast object of type 'System.Web.UI.Triplet' to type 'System.Object[]'.]   System.Web.Mvc.AntiForgeryDataSerializer.Deserialize(String serializedToken) +104[HttpAntiForgeryException (0x80004005): A required anti-forgery token was not supplied or was invalid.]   System.Web.Mvc.AntiForgeryDataSerializer.Deserialize(String serializedToken) +368   System.Web.Mvc.HtmlHelper.GetAntiForgeryTokenAndSetCookie(String salt, String domain, String path) +209   System.Web.Mvc.HtmlHelper.AntiForgeryToken(String salt, String domain, String path) +16   System.Web.Mvc.HtmlHelper.AntiForgeryToken() +10  <snip> So you've just kicked all your active users out of your site with exceptions until they think to restart their browser (to clear the session cookies). The only work around for now is to either write some code that wipes this cookie - or disable use of AntiForgeryToken() in your MVC 2.0 site until you're confident all session cookies will have expired. That in itself isn't very straightforward, given how frequently people tend to hibernate/standby their machines - the session cookie will only clear once the browser has been shut down and re-opened. Hope this helps someone out there!

• BizTalk 2010 upgrade - Sunset Development/Deployment Modes

  - by Ahsan Alam

  Those who are familiar with BizTalk 2006, should know about Development and Deployment modes in Visual Studio. Personally, I never questioned why it's not Debug and Release just like everything else in Visual Studio. Then everything changed in BizTalk 2010. BizTalk and Visual Studio 2010 now uses Debug and Release modes by default. When we upgraded BizTalk 2006 solution to 2010, Development and Deployment modes remained unchanged for all the projects, and code compiled without any issues. Soon, I realized that any new projects added to the converted solutions started using Debug and Release modes. This also didn't cause any problem compiling the solution from Visual Studio; however, it broke our custom build/deployment scripts since the scripts were trying to build in Deployment mode. So, I decided to change all projects from Development and Deployment modes to Debug and Release modes to keep them consistent. During this process I realized that Debug and Release modes are defaults; but it's completely customizable. During the BizTalk 2010 upgrade process, I figured that switching to default Debug and Release modes are the best options.

• Unable to mount an LVM Hard-drive after upgrade

  - by Bruce Staples

  I imagine this is a basic gotcha ... but I can't see it. I have a system with 2(physical) harddrives. The boot system (/dev/sda) was running 10.04 & the second drive (/dev/sdb) was just a mounted filesystem. I did a clean load of Ubuntu 12.04 overwriting /dev/sda (not an upgrade) & now cannot mount the second drive. so I do not know what to enter it into the fstab ... I had expected to use: /dev/sdb /tera ext4 defaults 0 2 But even manual mounting fails (I also have tried various "-t" options on the off chance!) sudo mount -t ext4 /dev/sdb1 /tera mount: wrong fs type, bad option, bad superblock on /dev/sdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so Output from disk queries indicate that it is a Linux LVM & a healthy disk still. sudo lshw -C disk *-disk:0 description: ATA Disk product: WDC WD5000AACS-0 vendor: Western Digital physical id: 0 bus info: scsi@2:0.0.0 logical name: /dev/sda version: 01.0 serial: WD-WCASU1401098 size: 465GiB (500GB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 signature=00015a55 *-disk:1 description: ATA Disk product: WDC WD10EADS-00L vendor: Western Digital physical id: 1 bus info: scsi@3:0.0.0 logical name: /dev/sdb version: 01.0 serial: WD-WCAU47836304 size: 931GiB (1TB) capabilities: partitioned partitioned:dos configuration: ansiversion=5 sudo fdisk -l Disk /dev/sda: 500.1 GB, 500106780160 bytes 255 heads, 63 sectors/track, 60801 cylinders, total 976771055 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00015a55 Device Boot Start End Blocks Id System /dev/sda1 * 2048 972580863 486289408 83 Linux /dev/sda2 972582910 976769023 2093057 5 Extended /dev/sda5 972582912 976769023 2093056 82 Linux swap / Solaris Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdb1 1 1953525167 976762583+ 8e Linux LVM LVM doesn't appear to be an option for mount or fstab. ... and here's a Smart data Screenshot from Disk Utility.

• Java JRE 7 Automatic Upgrade and Demantra Requirements - Action Required

  - by user702295

  The following applies to ALL Demantra, EBS and Demantra Oracle Integrations: All EBS desktop administrators must disable JRE Auto-Update for their end-users immediately. See this externally-published article:     URGENT BULLETIN: Disable JRE Auto-Update for All E-Business Suite End-Users     https://blogs.oracle.com/stevenChan/entry/bulletin_disable_jre_auto_update Why is this required? If you have Auto-Update enabled, your JRE 1.6 version will be updated to JRE 7.     This may happen as early as July 3, 2012.     This will definitely happen after Sept. 7, 2012, after the release of 1.6.0_35 (6u35).  Oracle Forms is not compatible with JRE 7 yet.  JRE 7 has not been certified with Oracle E-Business Suite yet. Oracle E-Business Suite functionality based on Forms -- e.g. Financials -- will stop working if you upgrade to JRE 7. Related News Java 1.6.0_33 is certified with Oracle E-Business Suite.  See this externally-published article:     Java JRE 1.6.0_33 Certified with Oracle E-Business Suite     https://blogs.oracle.com/stevenChan/entry/jre_1_6_0_33

• virtual box upgrade

  - by Husni

  I did upgrade virtualbox from 4.1 to 4.2 wheneverver I want to load my win xp vdi, it gives me the following error: "Kernel driver not installed (rc=-1908) The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing '/etc/init.d/vboxdrv setup' as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary." I ran the suggested step to reinstall the kernel module, and the log file files is as follow: Makefile:181: * Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR= and run Make again. Stop. Makefile:181: * Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR= and run Make again. Stop. Makefile:181: * Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR= and run Make again. Stop. I still unable to re-run my win virtual XP vdi file. anyone have a clue?

• SD card won't appear after upgrade to 13.10

  - by Pixel

  My SD card won't mount when I put it into my lap top, everything was fine before the upgrade. The information about the SD card appears just fine when I type "sudo fdisk l " it just says that it doesn't have a valid partition table. When I type "_sudo blkid" I get the following answer: /dev/sda1: UUID="CCA8-9030" TYPE="vfat" /dev/sda2: UUID="8a1d135b-384b-432d-b608-64dcf09ada24" TYPE="ext2" /dev/sda3: UUID="7s6PtU-kj2Z-N8XD-0mzl-840i-i3HG-enlbAf" TYPE="LVM2_member" /dev/sr0: LABEL="Bamboo CD" TYPE="iso9660" /dev/mapper/ubuntu--vg-root: UUID="c9b521c8-7c9f-493b-95c8-a7d79c465318" TYPE="ext4" /dev/mapper/ubuntu--vg-swap_1: UUID="7f155ab6-e1b9-485b-a2bc-443c0622284d" TYPE="swap" When I use lsusb: Bus 002 Device 002: ID 8087:0024 Intel Corp.

Also I can't erase what's on the card, it contains important data which I need... :/ If you need anymore information just ask, I'll give it as soon as I can. Pixel.

• dist-upgrade runs and completes but current kernel stays the same

  - by jaguare22

  I think that my system is staying at an older kernel version. It seems to update when I run dist-upgrade but the current kernel version doesn't change. Is it possible the system is set to install new kernel updates but only load an older version at start up? $ uname -a Linux HTPC 3.2.0-32-generic #51-Ubuntu SMP Wed Sep 26 21:32:50 UTC 2012 i686 athlon i386 GNU/Linux $ dpkg --list | grep linux-image ii linux-image-3.2.0-32-generic 3.2.0-32.51 Linux kernel image for version 3.2.0 on 32 bit x86 SMP ii linux-image-3.2.0-32-generic-pae 3.2.0-32.51 Linux kernel image for version 3.2.0 on 32 bit x86 SMP ii linux-image-3.2.0-32-virtual 3.2.0-32.51 Linux kernel image for version 3.2.0 on 32 bit x86 Virtual Guests dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' linux-headers-3.2.0-36 linux-headers-3.2.0-36-generic-pae linux-headers-3.2.0-37 linux-headers-3.2.0-37-generic-pae linux-headers-3.2.0-38 linux-headers-3.2.0-38-generic-pae linux-headers-3.2.0-39 linux-headers-3.2.0-39-generic-pae linux-headers-3.2.0-40 linux-headers-3.2.0-40-generic-pae linux-headers-3.2.0-41 linux-headers-3.2.0-41-generic-pae linux-headers-3.2.0-43 linux-headers-3.2.0-43-generic-pae linux-headers-3.2.0-44 linux-headers-3.2.0-44-generic-pae linux-headers-3.2.0-45 linux-headers-3.2.0-45-generic-pae linux-headers-3.2.0-48 linux-headers-3.2.0-48-generic-pae

• Desktop goes un-usable after upgrade to 12.04

  - by Tom Nail

  I have multiple Ubuntu systems connected to a KVM, one of which I recently upgraded from Ubuntu 10 to 12.04. After the upgrade, this system desktop does fine until it is allowed to go to idle (i.e., I've switched to another system on the KVM and it locks it's desktop). When I come back to it, the screen is garbled and paging across at a rate seemingly determined by the mouse. Although no pointer is visible, I can get the screen to stop paging (and just be garbled) by moving the mouse left and right. The paging will slow down and come to a stop, if I can align things carefully enough. This condition persists even when I try to go to a CLI-based login (e.g., CTRL+Alt+F1) and will continue until I reboot the machine. Unfortunately, I'm not very familiar with the Unity desktop, so I don't know where to find things to troubleshoot. A restart of lightdm doesn't change anything, so I'm wondering if this might be more hardware based( although this machine hasn't given me any trouble previously in the same setup). The .xsession-errors file has some issues with compiz, nautilus and GConf listed, but I'm not sure those are actually germane to the issue. Thanks for any help, -=Tom

• How do I upgrade from ubuntu 9.10 to 12.10 on my Acer Aspire 3000

  - by 770

  I had my Acer Aspire 3000 as a dual boot XP/ubuntu 9.10 a couple years ago. I recently blew the dust of it and wanted to upgrade to 7/Ubuntu 12.10 so I began by formatting the Ubuntu side of the partition and apparently damaged the mbr as I could only get black screen with the error message: GRUB loading. error: no such partition grub rescue I then slaved the hdd to my win7 desktop and formatted the entire drive, both sides of the partition then reinstalled it in the Acer and tried to install win7. Upon starting the Acer I got the same error message: GRUB loading. error: no such partition grub rescue I then tried to reinstall Ubuntu 9.10 as I have an Ubuntu produced installation cd. Same result. Next day I received a new battery I had ordered for the Acer. I plugged it and the power supply in and hit the power button just to see if I at least could charge the battery but to my surprise Ubuntu 9.10 began to install, so I let it and it did. Now the hard drive shows 58 gb and 2.5gb partitions neither of which is formatted NTFS for/by windows. I am guessing that the GRUB/mbr was repaired somehow by the Ubuntu reinstallation. My question, should you choose to accept it; How can I get to my goal of dual boot win7/Ubuntu 12.10. I am a beginner and don't know much about linux or the terminology. Thank you for your thoughts and help.
