• Unmet dependencies when trying to install openssh-server

  - by Sabiya

  I am running sudo-apt get install openssh-server on Ubuntu 12.04 64 bit system. It is giving me the following output. $ sudo apt-get install openssh-server Reading package lists...

• How do I install Pencil?

  - by Rich

  Pencil either runs as a Firefox extension or as a standalone application with XULRunner 1.9.2.

Done Building dependency tree Reading state information... Done Package xulrunner-1.9.2 is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'xulrunner-1.9.2' has no installation candidate So I tried to install it using Firefox by clicking on the install button on the Pencil home page, and the .xpi file was downloaded and opened by an archive manager. Any ideas?

• How to install Awesome WM without root access?

  - by ssice

  I want to install the Awesome window manager. In the environment where I want to configure it I don't have root access. I do have a machine were I can be root (I use for this a virtual machine in my laptop). I have tried the following: $ sudo apt-get install awesome The following packages are about to be installed: awesome libev3 libid3tag0 libimlib2 liblua5.1-0 libxcb-icccm1 libxcb-image0 libxcb-keysyms1 libxcb-property1 libxcb-randr0 libxcb-xinerama0 libxcb-xtest0 libxdg-basedir1 menu rlwrap Do you want to continue [Y/n]? n I do now have the list of dependencies for awesome, so I downloaded them all. For that, I did the following. $ pkgs="awesome libev3 libid3tag0 libimlib2 liblua5.1-0 libxcb-icccm1 libxcb-image0 libxcb-keysyms1 libxcb-property1 libxcb-randr0 libxcb-xinerama0 libxcb-xtest0 libxdg-basedir1 menu rlwrap" # this is just for not writing it all ;) $ sudo apt-get install --download-only $pkgs .... $ mkdir -p /tmp/x_debs $ for pkg in $pkgs; do cp /var/cache/apt/archives/$pkg* /tmp/x_debs/; done [ copies all *.deb from my dependencies to /tmp/x_debs ] Now, I want to install the dependencies. For that, I setup a fake dpkg install in my home folder: $ mkdir $HOME/root $ mkdir -p $HOME/root/var/lib/dpkg/{triggers,updates} $ touch $HOME/root/var/lib/dpkg/{available,status} Now I tried to install with dpkg, but I could not: $ dpkg --force-not-root --root=$HOME/root --recursive -i /tmp/x_debs It failed while trying to set permissions for the packages and running chroot. As I do have root access in this machine, I ran it with privileges: $ sudo dpkg --root=$HOME/root --recursive -i /tmp/x_debs Then I had a lot of stuff (i.e., everything: dependencies and the own WM) installed inside $HOME/root. Particularly, xcb-* libraries were installed in $HOME/root/usr/lib and the awesome binary in $HOME/root/usr/bin/awesome. If I try to execute awesome as is I get as an error that libraries could not be loaded. That's normal, as they are not in /usr/lib nor in /lib. So I ran export LD_LIBRARY_PATH=$HOME/root/usr/lib:$HOME/root/lib:${LD_LIBRARY_PATH} and awesome would try to load. However, I could not make gdm to run awesome within gnome or replacing it. I did it this way so I can copy everything in my $HOME/root folder, paste it in the other machine and have it running. Is there any other way (to have less wasted space maybe..) to do this? How can I tell gdm to exec awesome without root access?

• Install Ubuntu 12.04 on a ACER AC100

  - by pidarn

  I'm trying to install a 12.04.1 on an ACER AC100 - Mini-Server. After booting from the Install-CD there are no Disks shown. In Bios I disabled the Intel-Raid /LSI-Raid. I want to install on the 1st of 4 "native" disks and I tried to do this with RHEL 6.4 where all Disks are visible - but the UBUNTU-Installer doesn't find any of them. btw ... If I boot from the UBUNTU - Install-CD in "rescue"-mode the disks are visible?! Any Ideas?

• Doesn't installing "All locales" install necessary fonts too?

  - by its_me

  I recently noticed that my browsers rendered blank text (or invisible text?) on some websites in foreign languages, like Chinese. inside.com.tw, for example. Later I learnt that by default Debian only installs one locale (the one you choose during the installation process), and others need to be installed manually. So, I ran the command: # dpkg-reconfigure locales And selected All locales from the options screen that followed, and proceeded with the rest of the process, which also includes changing the default locale (which I set to en_US.UTF-8). Then I restarted my system. I still can't read the website that I mentioned earlier (inside.com.tw). Most of the text is blank, i.e. invisible. With the page translated by Chrome to my default language (en_US), the text is visible; BUT not in the original language. Why is this happening? Does this mean that installing locales isn't actually necessary, and all I have to do is install the fonts for all supported languages? If so, how do I install all the fonts necessary for All locales? UPDATE: An easy fix is to install the unifont package which adds support for all Unicode 5.1 characters. But the rendering is of very bad quality. So, how I install all font packages? I notice that there are three sets, ones starting with fonts-*, another with xfonts-*, and ttf-*? Which set should I exactly go with, and how do I install that set of fonts. Looking for a knowledgeable solution.

• I cannot solve the "Install these packages without verification" problem

• I can't install Ubuntu on my Dell Inspiron 15R at all

  - by Kieran Rimmer

  I'm attempting to install Ubuntu 12.04LTS, 64 bit onto a Dell Inspiron 15R laptop. I've shrunk down one of the windows partitions and even used gparted to format the vacant space as ext4. However, the install disk simply does not present any options when it comes to the partitioning step. What I get is a non-responsive blank table As well as the above, I've changed the BIOS settings so that USB emulation is disabled (as per Can't install on Dell Inspiron 15R), and changed the SATA Operation setting to all three possible options. Anyway, the install CD will bring up the trial version of ubuntu, and if I open terminal and type sudo fdisk -l, I get this: Disk /dev/sda: 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 / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xb4fd9215 Device Boot Start End Blocks Id System /dev/sda1 63 80324 40131 de Dell Utility Partition 1 does not start on physical sector boundary. /dev/sda2 * 81920 29044735 14481408 7 HPFS/NTFS/exFAT /dev/sda3 29044736 1005142015 488048640 7 HPFS/NTFS/exFAT /dev/sda4 1005154920 1953520064 474182572+ 83 Linux Disk /dev/sdb: 32.0 GB, 32017047552 bytes 255 heads, 63 sectors/track, 3892 cylinders, total 62533296 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: 0xb4fd923d Device Boot Start End Blocks Id System /dev/sdb1 2048 16775167 8386560 84 OS/2 hidden C: drive If I type 'sudo parted -l', I get: Model: ATA WDC WD10JPVT-75A (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/4096B Partition Table: msdos Number Start End Size Type File system Flags 1 32.3kB 41.1MB 41.1MB primary fat16 diag 2 41.9MB 14.9GB 14.8GB primary ntfs boot 3 14.9GB 515GB 500GB primary ntfs 4 515GB 1000GB 486GB primary ext4 Model: ATA SAMSUNG SSD PM83 (scsi) Disk /dev/sdb: 32.0GB Sector size (logical/physical): 512B/512B Partition Table: msdos Number Start End Size Type File system Flags 1 1049kB 8589MB 8588MB primary Warning: Unable to open /dev/sr0 read-write (Read-only file system). /dev/sr0 has been opened read-only.

• How to install drivers for NVIDIA GeForce FX 5200 on Precise

  - by Aaron Simmons

  Ok, I'm a total Linux noob. I was able to install 12.4 without issue, except that it says in the system settings that the graphics card/driver is "unknown". I have NVIDIA GeForce FX 5200, and have not been able to get it installed. I've found the driver at NVIDIA but couldn't figure out how to actually install it. I found instructions that used apt-get to automatically find the current driver and install it, and that came close. At least then it showed up in the 3rd party drivers list. It said it was installed but not being used? And I was unable to find out why that might be, or how to get the system to use it Two questions: 1. CAN/SHOULD my graphics card work with 12.4? 2. If so, HOW? I'm running a 100% fresh install, so what's the step-by-step from there?

• Windows 8 fresh install and 12.10 dual boot

  - by Sir Linuxalot

  I have a question concerning Windows 8 and dual booting with Ubuntu 12.10. I've researched answers here, but haven't seen a question that resembles mine exactly: Ubuntu install and dual Boot with Windows 8 UEFI UEFI hardware and dual booting with windows Ubuntu 12.10 wont boot Specifically, I'm pondering installing a fresh install of Windows 8 (for game purposes), and a fresh install of 12.10 and dual booting them. I'm not sure if UEFI is hardware specific or software specific, and I'm worried if I try to implement the dual boot I'm going to run into UEFI issues and have to go through the grief of getting things up and running by following a long and tedious procedure. Can I, starting with Windows 8, then install 12.10 without too much hassle? My current hardware config is: Microstar Motherboard 7514 with an Intel Core 2 Duo processor. The drive I'm thinking of using is a Western Digital TB drive, new out of the box. As always, any help would be appreciated. Thanks.

• Can't Select Continue to install ubuntu alongside them

  - by msknapp

  I'm trying to install ubuntu 14.04 alongside Window 7 on my PC. I got to the installation type page and it detected my windows 7, then asked me what I would like to do. I selected the option to install ubuntu alongside them; however, the continue button was then grayed out. If instead I chose the option to do something else, the continue button was still grayed out. I was given absolutely no explanation for why it was grayed out. The only option that would let me continue was to erase the disk, which I do not want to do. I have two hard disks, and one of them has two partitions on it. The second partition is completely unused, and has a terabyte of space. That's where I wanted to install it. Can somebody please tell me why I can't install ubuntu alongside Windows 7 here?

• Windows XP self-installing virus [closed]

  - by Oliver

  Do you remember. Some years ago, there was a huge virus attacking Windows XP in its first version. Once you had installed Windows XP, and on your first internet access, the virus installed itself on your computer, closing your internet connection and making the computer reboot after some seconds. I wonder... How can a virus install itslef this way from nowhere ? Without any user action. You install Windows XP... the computer just connects itself to the internet (assuming Microsoft don't connect to bad sites on its first connection)... and you have a virus. There is something magic I don't understand here. Can someone explain me how that virus could attack Windows that way, without any user action on a fresh installed system...

• Web Apps vs Web Services: 302s and 401s are not always good Friends

  - by Your DisplayName here!

  It is not very uncommon to have web sites that have web UX and services content. The UX part maybe uses WS-Federation (or some other redirect based mechanism). That means whenever an authorization error occurs (401 status code), this is picked by the corresponding redirect module and turned into a redirect (302) to the login page. All is good. But in services, when you emit a 401, you typically want that status code to travel back to the client agent, so it can do error handling. These two approaches conflict. If you think (like me) that you should separate UX and services into separate apps, you don’t need to read on. Just do it ;) If you need to mix both mechanisms in a single app – here’s how I solved it for a project. I sub classed the redirect module – this was in my case the WIF WS-Federation HTTP module and modified the OnAuthorizationFailed method. In there I check for a special HttpContext item, and if that is present, I suppress the redirect. Otherwise everything works as normal: class ServiceAwareWSFederationAuthenticationModule : WSFederationAuthenticationModule {     protected override void OnAuthorizationFailed(AuthorizationFailedEventArgs e)     {         base.OnAuthorizationFailed(e);         var isService = HttpContext.Current.Items[AdvertiseWcfInHttpPipelineBehavior.DefaultLabel];         if (isService != null)         {             e.RedirectToIdentityProvider = false;         }     } } Now the question is, how do you smuggle that value into the HttpContext. If it is a MVC based web service, that’s easy of course. In the case of WCF, one approach that worked for me was to set it in a service behavior (dispatch message inspector to be exact): public void BeforeSendReply( ref Message reply, object correlationState) {     if (HttpContext.Current != null)     {         HttpContext.Current.Items[DefaultLabel] = true;     } } HTH
