Specify ubuntu repository from which a package is installed?

  • 772

I want to install ffmpeg from mediubuntu. I've installed the repository per the instructions on:

http://medibuntu.org/repository.php

My conf.d repository listing:

/etc/apt/sources.list.d# less medibuntu.list  
## Please report any bug on https://bugs.launchpad.net/medibuntu/
deb http://packages.medibuntu.org/ lucid free non-free #Medibuntu - Ubuntu 10.04 "lucid lynx"
#deb-src http://packages.medibuntu.org/ lucid free non-free #Medibuntu (source) - Ubuntu 10.04 "lucid lynx"

Yet when I install ffmpeg I still get it installed via the main ubuntu library. 

/etc/apt/sources.list.d# apt-cache policy ffmpeg
ffmpeg:
 Installed: (none)
 Candidate: 4:0.5.1-1ubuntu1
 Version table:
   4:0.5.1-1ubuntu1 0
     500 http://archive.ubuntu.com/ubuntu/ lucid/main Packages

(Ignore the installed: none; I've installed/purged multiple times trying to get the medibuntu one)

Is there a way I can force it to use the medibuntu repository? Perferably at run-time rather than in a config file.

ubuntu apt ffmpeg repository

  1. As Zoredache mentioned, it's not showing as available from anywhere but main; it needs to be there before this will work. That said, you'll want to look into using pinning to set the origin used for a given package.

    Edit /etc/apt/preferences, and add a block something like this:

    Package: ffmpeg
Pin: origin packages.medibuntu.org
Pin-Priority: 600
