How can I specify the repository from which a package will be installed? (emacs-snapshot)
I want to install emacs-snapshot from http://emacs.orebokech.com But there is already an emacs-snapshot in Ubuntu's repositories.
How can I specify the repository from which a package will be installed?
You can specify a repository with -t
option. As an example, I have added the following repository to /etc/apt/sources.list
to install Iceweasel latest release:
deb http://mozilla.debian.net/ squeeze-backports iceweasel-release
As you know there is a same package iceweasel
in the official Debian repository. If I want install Iceweasel from this specific repo I run:
apt-get install -t squeeze-backports iceweasel
from apt-get manual page:
-t, --target-release, --default-release
This option controls the default input to the policy engine, it creates a default pin at priority 990 using the specified
release string. This overrides the general settings in /etc/apt/preferences. Specifically pinned packages are not affected by
the value of this option. In short, this option lets you have simple control over which distribution packages will be retrieved
from. Some common examples might be -t '2.1*', -t unstable or -t sid. Configuration Item: APT::Default-Release; see also the
apt_preferences(5) manual page.
I think this is a better solution,

I found a workaround. First I needed to find the repositories that had the pacakage:
$ apt-cache showpkg emacs-snapshot
Package: emacs-snapshot
Versions:
1:20100111-1~lenny1 (/var/lib/apt/lists/emacs.orebokech.com_dists_lenny_main_binary-amd64_Packages) (/var/lib/dpkg/status)
Description Language:
File: /var/lib/apt/lists/emacs.orebokech.com_dists_lenny_main_binary-amd64_Packages
MD5: 906df684c212eabe267e6b5c2e8c2032
1:20090909-1 (/var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_karmic_universe_binary-amd64_Packages)

In the Versions: section. I see the versions that come from different repositories:
- 1:20100111-1~lenny1
- 1:20090909-1
So now we just tell apt or aptitude to install that specific version:
$ sudo aptitude install emacs-snapshot=1:20100111-1~lenny1
package-name=version_name
Victory.
I still don't know how to use a specific repository. But in this case a specific version was enough.
