  I've got a pluscom pci card plugged into my desktop and although the mac address shows up in network manager, it says "Wireless unavailable".

• rkhunter: right way to handle warnings further?

  - by zuba

  I googled some and checked out two first links it found: http://www.skullbox.net/rkhunter.php http://www.techerator.com/2011/07/how-to-detect-rootkits-in-linux-with-rkhunter/ They don't mention what shall I do in case of such warnings: Warning: The command '/bin/which' has been replaced by a script: /bin/which: POSIX shell script text executable Warning: The command '/usr/sbin/adduser' has been replaced by a script: /usr/sbin/adduser: a /usr/bin/perl script text executable Warning: The command '/usr/bin/ldd' has been replaced by a script: /usr/bin/ldd: Bourne-Again shell script text executable Warning: The file properties have changed: File: /usr/bin/lynx Current hash: 95e81c36428c9d955e8915a7b551b1ffed2c3f28 Stored hash : a46af7e4154a96d926a0f32790181eabf02c60a4 Q1: Is there more extended HowTos which explain how to deal with different kind warnings? And the second question. Were my actions sufficient to resolve these warnings? a) To find the package which contains the suspicious file, e.g. it is debianutils for the file /bin/which ~ > dpkg -S /bin/which debianutils: /bin/which b) To check the debianutils package checksums: ~ > debsums debianutils /bin/run-parts OK /bin/tempfile OK /bin/which OK /sbin/installkernel OK /usr/bin/savelog OK /usr/sbin/add-shell OK /usr/sbin/remove-shell OK /usr/share/man/man1/which.1.gz OK /usr/share/man/man1/tempfile.1.gz OK /usr/share/man/man8/savelog.8.gz OK /usr/share/man/man8/add-shell.8.gz OK /usr/share/man/man8/remove-shell.8.gz OK /usr/share/man/man8/run-parts.8.gz OK /usr/share/man/man8/installkernel.8.gz OK /usr/share/man/fr/man1/which.1.gz OK /usr/share/man/fr/man1/tempfile.1.gz OK /usr/share/man/fr/man8/remove-shell.8.gz OK /usr/share/man/fr/man8/run-parts.8.gz OK /usr/share/man/fr/man8/savelog.8.gz OK /usr/share/man/fr/man8/add-shell.8.gz OK /usr/share/man/fr/man8/installkernel.8.gz OK /usr/share/doc/debianutils/copyright OK /usr/share/doc/debianutils/changelog.gz OK /usr/share/doc/debianutils/README.shells.gz OK /usr/share/debianutils/shells OK c) To relax about /bin/which as I see OK /bin/which OK d) To put the file /bin/which to /etc/rkhunter.conf as SCRIPTWHITELIST="/bin/which" e) For warnings as for the file /usr/bin/lynx I update checksum with rkhunter --propupd /usr/bin/lynx.cur Q2: Do I resolve such warnings right way?

• How to Set Ubuntu 12.04 to it's factory settings like when u first installed it?

  - by Cameron

  Well, this is a simple answered question, from the title, but my real problem is hard af. I have set ubuntu to use root, then it wouldn't let me log into the admin account only root and guest I deleted the admin account, remade another, then attempted to disable root account. This failed - I messed up the password, the original password was "root" I also didn't set a password for my new admin account, so It says it has one, whats the default password for it? I can't moderate my ubuntu system at all now. I have tried to drop to cmd shell thing, it asks for the root password, i type 'root' and any other possible passwords, it doesn't work. To reset ubuntu to factory settings i have found that i could enter the following code: sudo dpkg-reconfigure -phigh -a sudo Requires admin password, that I cant find out without root password and I don;t know. My goal is to try to fix this without remaking a bootable usb for ubuntu, because I lost the one i made for this. so If i can't, please say so. If you can help thanks!

  I have a Ubuntu 12.04 server installed on my machine. I am trying to install request-tracker4. Here's what I have done so far : a) Installed request-tracker via "sudo apt-get install request-tracker4" b) I then tried configuring RT_SiteConfig.pm in /etc/request-tracker4 but then ran into problems in populating the MySQL database. c) I then did sudo dpkg-reconfigure request-tracker4 d) It solved my problems of not being able to populate / setup mysql etc. e) Now, I am trying to setup rt under www.mydomain.com/rt I have read various how-to's and bestpractical's own guides but I am not very much a expert in Apache configurations so stuck. My Current Ubuntu 12.04 server setup: Apache2, Fastcgi installed (checked in /etc/apache2/mods-enabled Web Server document root is default /var/www/ Web user www-data Question is : 1 ) Where and What shall I put in Apache configuration to start using RT via the web-interface ? I have seen two files in /etc/request-tracker4/ apache2-fastcgi.conf and apache2-fcgid.conf I even tried making a ln -s apache2-fastcgi.conf /etc/apache2/conf.d but when I tried opening that file in root while in the conf.d directory it said too many levels. Any request tracker experts on ubuntu ?:-) Your help will be very useful and appreciated Thanks Please let me know if you need further info !

• Remap keyboard Ubuntu 12.04; Asus Q500A

  - by hydroxide

  I have an Asus Q500A with win8 and Ubuntu 12.04 64 bit; linux kernel 3.8.0-32-generic. I am using gnome-panel, and xserver-xorg-lts-raring. I have been experiencing problems with the keyboard short-cuts since I had a fresh install. fn+f10 is supposed to mute my system, but instead it will repeatedly press d. fn+f11 is volume down, but it presses c. fn+f12 is volume up, presses b repeatedly. Most of the other on-board short-cuts such as adjusting screen and led brightness work most of the time, but sometimes press other letters repeatedly. Also, sometimes my cntr gets held down for no reason. Everything works fine in windows. I have tried installing all recommends and sudo dpkg-reconfigure -a to reconfigure all packages, which did not solve my problem. I have tried using KeyTouch editor to edit keymaps, navigating to /usr/shar/x11/xkb/keymap when I try opening any of these files it says file contains no keyboard element. I think If I were just able to remap my keyboard it might solve my issues, otherwise if anyone knows where I can get asus drivers for 12.04 please let me know Apparently I didn't have all repositories enabled. I executed the following commands and am trying the updates they give me. Getting linux_kernel 3.8.0-33 generic as well as a bunch of other packages. sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe" sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe restricted multiverse" sudo add-apt-repository "deb http://archive.canonical.com/ubuntu $(lsb_release -sc) partner"

• What is the proper way to install the 3.4 kernel?

  - by Marcelo Ruiz

  Kernel 3.2 has an annoying error for my wireless card (rtl8192se-b) that makes the connection drop and/or prevents the card to make a connection to the wireless router. Dealing with it was very frustrating until I found out the bug was corrected in 3.4. I downloaded: linux-headers-3.4.0-030400_3.4.0-030400.201205210521_all.deb linux-headers-3.4.0-030400_3.4.0-030400.201205210521_all.deb linux-image-3.4.0-030400-generic_3.4.0-030400.201205210521_amd64.deb and installed with: sudo dpkg -i * Now the wireless works fine, but I have two problems that cannot solve. The first one is minor: plymouth would not start at all. But if I boot with the 3.2 kernel it works fine. The second one is serious: sometimes the computer won't shut down or reboot. The X server terminates but the computer shows part of my grub background and will stay there forever using 100% of the CPU. I have a Toshiba Qosmio with an Core i7 and nvidia graphic card (using nvidia-current). During one shutdown, I briefly read a message that said that the virtualbox module couldn't be unloaded from the kernel. I tried to solve this by removing and purging virtualbox and installing it back. I don't see the message anymore, but sometimes the computer won't shutdown nor reboot. Am I missing something to properly configure the new kernels? Thanks!

• Failed to fetch *.deb Size mismatch, then packages with unmet dependencies [solved]

  - by user113907

  I recently bought the wonderfully looking and reviewed Amnesia The Dark Descent and I'm trying to install it. The first time I tried to download it, I had to stop in the middle of the download (may have broken something). The second time I tried to download, at the end of the download it gave me the following error: Failed to fetch https://private-ppa.launchpad.net/commercial-ppa-uploaders/amnesia/ubuntu/pool/main/a/amnesia/amnesia_1.2.1-0ubuntu2_i386.deb Size mismatch Now, whenever I try to download it, it gives me this error: The following packages have unmet dependencies: amnesia: Depends: libalut0 (>= 1.0.1) but it is not going to be installed Depends: libc6 (>= 2.4) but 2.15-0ubuntu10.3 is to be installed Depends: libfontconfig1 (>= 2.8.0) but 2.8.0-3ubuntu9.1 is to be installed Depends: libfreetype6 (>= 2.2.1) but 2.4.8-1ubuntu2 is to be installed Depends: libgcc1 (>= 1:4.1.1) but 1:4.6.3-1ubuntu5 is to be installed Depends: libopenal1 (>= 1:1.13) but 1:1.13-4ubuntu3 is to be installed Depends: libsdl1.2debian (>= 1.2.10-1) but 1.2.14-6.4ubuntu3 is to be installed Depends: libstdc++6 (>= 4.1.1) but 4.6.3-1ubuntu5 is to be installed Depends: libxft2 (> 2.1.1) but 2.2.0-3ubuntu2 is to be installed Depends: zlib1g (>= 1:1.1.4) but 1:1.2.3.4.dfsg-3ubuntu4 is to be installed I already searched the net and ran a few command line commands. Ex: sudo dpkg --configure -a sudo apt-get install -f Or configure the software packages to download from Main instead of the local UK server. But I'm really not figuring out a solution. I have a fresh install of the latest LTS (12.04). The only non-standard thing so far is that I installed gnome-shell (?) because I really can't stand Unity. Help would be much appreciated. I am currently more than entertained enough with World of Goo and Command & Conquer, but I will want to play Amnesia in the close future.

• create a .deb Package from scripts or binaries

  - by tdeutsch

  I searched for a simple way to create .deb Packages for things which have no source code to compile (configs, shellscripts, proprietary software). This was quite a problem because most of the package tutorials are assuming you have a source tarball you want to compile. Then I've found this short tutorial (german). Afterwards, I created a small script to create a simple repository. Like this: rm /export/my-repository/repository/* cd /home/tdeutsch/deb-pkg for i in $(ls | grep my); do dpkg -b ./$i /export/my-repository/repository/$i.deb; done cd /export/avanon-repository/repository gpg --armor --export "My Package Signing Key" > PublicKey apt-ftparchive packages ./ | gzip > Packages.gz apt-ftparchive packages ./ > Packages apt-ftparchive release ./ > /tmp/Release.tmp; mv /tmp/Release.tmp Release gpg --output Release.gpg -ba Release I added the key to the apt keyring and included the source like this: deb http://my.default.com/my-repository/ ./ It looks like the repo itself is working well (I ran into some problems, to fix them I needed to add the Packages twice and make the temp-file workaround for the Release file). I also put some downloaded .deb into the repo, it looks like they are also working without problems. But my self created packages didn't... Wenn i do sudo apt-get update, they are causing errors like this: E: Problem parsing dependency Depends E: Error occurred while processing my-printerconf (NewVersion2) E: Problem with MergeList /var/lib/apt/lists/my.default.com_my-repository_._Packages E: The package lists or status file could not be parsed or opened. Has anyone an idea what I did wrong?

I used to have bumblebee but then some website said to remove it and now something's clearly wrong. What's the right way to set things up? Should I try to add bumblebee back?

• nautilus crash when merging/overwriting files

  - by sBlatt

  On my Ubuntu 10.10, whenever I want to copy some files/folders over some other files/folders, or when I try to empty the trash, nautilus crashes! Example: I have a folder with some files. Now I want to overwrite this folder with a folder with the same name, same files, but some additional files, the merge window comes up, I choose merge and nautilus crashes (does not respond, when I press the close button I can force close it). Some times it even does the copying/emptying (trash), but it always crashes! This happens when copying to the same partition/ntfs partition/netshares, but not when I make a new folder and copy the files/folders into that (without overwriting anything). On a netshare, it's even possible to merge these files afterwards with another computer! dmesg/syslog/messages does not show any entry related to that problem. Does anyone have a solution for this very annoying problem? EDIT: dpkg -l nautilus* (see output in pastebin) EDIT2: I found out, nautilus already crashes before clicking replace/merge (as soon as the question appeares. In the video it's not entirely clear, that i click the cross before the force-close dialog appeares. Video of problem nautilus-debug-log.txt EDIT3: Filed bugreport: https://bugs.launchpad.net/ubuntu/+source/nautilus/+bug/678233

• System broken after installing Gtk+-3.4.1 with broadway backend enabled

  - by Roman D. Boiko

  I am running Ubuntu 11.10 from VirtualBox. I installed Gtk+ 3.4.1 (latest stable release) from sources with X11 and broadway backends enabled. In order to do that, I also installed latest versions of glib, libffi, libtiff, libjped, gdk-pixbuf, and pango. Each of them was configured with default options. I.e., they were installed to /usr/local (at least, I see respective folders in /usr/local/include). After reboot and login (regardless which user), desktop is grey for about 30 sec, nothing is displayed. Then Nautilus starts, but nothing else (my locale is Ukrainian, but there is nothing important in text): . During boot, I can access command prompt as root, use dpkg, etc. But I don't know what to do. One idea is to reinstall Gtk+ and other libraries with prefix /usr or /usr/shared. I will try that, but it is quite time-consuming, so any ideas would be welcome. Reverting to earlier snapshot is still possible, but it is 6 days old and I would like to try to solve the problem.

• "sha256sum mismatch jdk-7u3-linux-x64.tar.gz " error when trying to install Oracle Java

  - by Fawkes5

  i recently tried installed java 7 on ubuntu 12.04 and i think i screwed something up I followed the instructions given here. First you need to remove openjdk for this run the following command from your terminal sudo apt-get purge openjdk* Now you can install Java7 by adding the following repository: sudo add-apt-repository ppa:eugenesan/java sudo apt-get update sudo apt-get install oracle-java7-installer Now everytime i install a new program i get the following error: Download done. sha256sum mismatch jdk-7u3-linux-x64.tar.gz Oracle JDK 7 is NOT installed. dpkg: error processing oracle-java7-installer (--configure): subprocess installed post-installation script returned error exit status 1 Setting up python-central (0.6.17ubuntu1) ...

Errors were encountered while processing: oracle-java7-installer Error in function: However.The program seems to install and work just fine so it doesn't seem to be a problem preventing me from doing anything So then i reinstalled openjdk by going: sudo apt-get install openjdk* But i still get the same error. going: sudo apt-get install oracle-java7-installer gives me the same error. What is going on? Please let me know if this is clear or not and ill try to explain my issue better

• Very large log files, what should I do?

  - by Masroor

  (This question deals with a similar issue, but it talks about a rotated log file.) Today I got a system message regarding very low /var space. As usual I executed the commands in the line of sudo apt-get clean which improved the scenario only slightly. Then I deleted the rotated log files which again provided very little improvement. Upon examination I find that some log files in the /var/log has grown up to be very huge ones. To be specific, ls -lSh /var/log gives, total 28G -rw-r----- 1 syslog adm 14G Aug 23 21:56 kern.log -rw-r----- 1 syslog adm 14G Aug 23 21:56 syslog -rw-rw-r-- 1 root utmp 390K Aug 23 21:47 wtmp -rw-r--r-- 1 root root 287K Aug 23 21:42 dpkg.log -rw-rw-r-- 1 root utmp 287K Aug 23 20:43 lastlog As we can see, the first two are the offending ones. I am mildly surprised why such large files have not been rotated. So, what should I do? Simply delete these files and then reboot? Or go for some more prudent steps? I am using Ubuntu 14.04.

• How do I fix the HDMI/DVI display output with Intel HD 4000 Graphics in 12.04?

  - by YumYumYum

  I have an Alienware Dell PC with Intel HD 4000 Graphics (Ivy Bridge) as verified by the output of lspci | grep VGA posted below. 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) The PC only has HDMI and DVI display outputs and using the HDMI output I am only being offered abnormal resolutions. As you can see below it does not even list HDMI1 or DVI1 but just only a fallback. $ export DISPLAY=:0.0 && xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1360 x 768, maximum 1360 x 768 default connected 1360x768+0+0 0mm x 0mm 1360x768 0.0* 1024x768 0.0 800x600 0.0 640x480 0.0 How can I fix this? Does it just need to be configured differently or will I need to use a newer kernel (as Intel Graphics drivers are included in the kernel)? Follow up: kernel to latest Step 1: Go to: http://kernel.ubuntu.com/~kernel-ppa/mainline/ Go to last: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/ Download: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/linux-headers-3.6.0-030600rc3-generic_3.6.0-030600rc3.201208221735_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/linux-headers-3.6.0-030600rc3_3.6.0-030600rc3.201208221735_all.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/linux-image-3.6.0-030600rc3-generic_3.6.0-030600rc3.201208221735_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc3-quantal/linux-image-extra-3.6.0-030600rc3-generic_3.6.0-030600rc3.201208221735_amd64.deb Step 2: sudo dpkg -i linux*.deb Step 3: reboot which shows that i have Ubuntu 12.04 with latest $ uname -a Linux sun-Alienware-X51 3.6.0-030600rc3-generic #201208221735 SMP Wed Aug 22 21:36:32 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux But still same problem remain.

• Ubuntu 10.04 hung on unattended apt-get upgrade?

  - by hafichuk

  I'm looking into why our ubuntu web server hung this morning and see that there was some package upgrades a few hours prior to the problem. I was able to ssh into the system and get a snapshot from top: top - 08:13:54 up 210 days, 8:25, 2 users, load average: 433.30, 422.40, 375.70 Tasks: 1192 total, 381 running, 810 sleeping, 0 stopped, 1 zombie Cpu(s): 0.5%us, 6.1%sy, 0.0%ni, 93.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 49549772k total, 48518392k used, 1031380k free, 960152k buffers Swap: 11595768k total, 279368k used, 11316400k free, 39355664k cached This is a 16 processor system, so I would typically expect a load in the low teens. I tried to restart apache, which didn't work, and subsequently had to do a hard reboot to get it working again (which it is). One thing I found was that the server did an unattended package update. Is it possible that upgrading php or curl (which our web sites use) might have caused apache to stop responding? Here is the snip from the unattended-upgrades.log from this morning: 2012-09-18 06:48:30,076 INFO Initial blacklisted packages: 2012-09-18 06:48:30,076 INFO Starting unattended upgrades script 2012-09-18 06:48:30,077 INFO Allowed origins are: ["['Ubuntu', 'lucid-security']"] 2012-09-18 06:49:37,017 INFO Packages that are upgraded: gnupg-curl php5-dev linux-server dhcp3-common linux-libc-dev php5-curl gpgv gnupg linux-headers-server linux-image-server php5 php5-mysql php-pear php5-cli php5-common libapache2-mod-php5 dhcp3-client 2012-09-18 06:49:37,018 INFO Writing dpkg log to '/var/log/unattended-upgrades/unattended-upgrades-dpkg_2012-09-18_06:49:37.017909.log'

• Network print to brother MFC-7420

  - by trampster

  I am trying to pint to a Brother MFC-7420 from my ubuntu 10.04 machine. The brother is attached to a windows XP machine and is shared. This is what I have tried: System-Administration-Printing, Add, Expand Network Printer, Windows Printer via SAMBA, Browse (I can find the printer no problems here), Foward, Choose Driver Dialog, Brother, My printer is not in this list So the next thing I tried was to download the printer driver from here http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/download_prn.html The driver installed fine but my printer still does not appear in the list. I also tried installing the cups wrapper but that gave the following error. Restarting Common Unix Printing System: cupsd [ OK ] cp: cannot stat `/usr/share/cups/model/MFC7420.ppd': No such file or directory dpkg: error processing cupswrappermfc7420 (--install): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: cupswrappermfc7420 I tried connecting the printer directly but even though I have installed the driver, when I go to printers and click on the printer (it shows up fine as a USB printer) then it say searching for drivers and then gives me a list, this is the same list as before which doesn't have my printer. It really shouldn't be this hard. on window you don't have to installing anything it just works and the same is true for my brothers Mac. How do I print to my printer?

• Install a i386 printer driver into an amd64 distribution or how can I find a good printer based on features?

  - by Yanick Rochon

  Hi, I just bought a Lexmark Interpret S408 all-in-one printer. The box said that it supported Ubuntu 8.04, but I told myself it should work with Lucid... well no. The only driver I have found is for i386 while I have a amd64 image installed; the architecture is incompatible. So, the quesiton is : Is it possible to install that driver anyway, somehow? Or do I need to take that printer back to the store and buy another one? If the latter is the only alternative, I need a printer that has wireless connection capability can do color printing is of good price (less than $200 CAD) Thank you for your answers, help, and tips. ** UPDATE ** The driver was given in the form of deb package (for Debian distributions) and I managed to extract the actual deb package driver out of the install program. I ran sudo dpkg -i --force-all lexmark-inkjet-09-driver-1.5-1.i386.deb and the driver installed, and I was able to print something out. But that pretty much ends there; I cannot access anymore of the printer settings, etc. (i.g. scanner, fax, wifi settings, etc.) I should suffice for now as I'm satisfied with the printer's features (and size, and prince), but if I could have a full-linux-supported printer like that one, I would return this one in exchange for the other.
