View Full Version : [ubuntu] Pinning repositories not being used properly in apt-get dist-upgrade -s

I'm having a unique issue involving apt pinning and apt-get reporting an incorrect repository. There is a package that has the same version in 2 different repositories (precise-updates and precise-security). Even though I have the Apt Pinning/Preferences configured properly and apt-cache policy reporting the correct information, apt-get dist-upgrade -s is not reporting the correct repository. This becomes an issue when trying to determine if a package/version is a security update or not.

root@server:~# cat /etc/apt/preferences.d/pin-precise-updates-release
Package: *
Pin: release a=precise-updates
Pin-Priority: 600

Package: *
Pin: release a=precise
Pin-Priority: 300

root@server:~# cat /etc/apt/preferences.d/pin-precise-security-release
Package: *
Pin: release a=precise-security
Pin-Priority: 900

root@server:~# sudo apt-get update
(output clipped)

root@server:~# sudo apt-cache policy linux-libc-dev
Installed: 3.2.0-53.81

Inst linux-libc-dev [3.2.0-53.81] (3.2.0-58.88 Ubuntu:12.04/precise-updates [amd64])
Conf linux-libc-dev (3.2.0-58.88 Ubuntu:12.04/precise-updates [amd64])

I would expect the last command to show Ubuntu:12.04/precise-security and not Ubuntu:12.04/precise-updates because of the higher repository priority. I have also found that if I put the precise-security source before precise-updates in /etc/apt/sources.list, apt-get dist-upgrade -s shows the precise-security repository.

Any ideas as to why this is happening?

Is anyone else seeing the same thing? I'm seeing this on 10+ of my Ubuntu 12.04 LTS servers. I'm not sure if this is a apt-get bug, Ubuntu bug, or something else. If anyone else is seeing this, I will open a bug.
