Bug#317186: apt: Pinning of individual packages does not work.

[Philipp Weis <pweis@pweis.com>]

Package: apt
Version: 0.6.38
Severity: normal

Hi,

apt doesn't respect the pin priority specified in
/etc/apt/preferences. With the attached file, I get

| # apt-cache policy aptitude
| aptitude:
|   Installed: 0.2.15.9-3
|   Candidate: 0.2.15.9-3
|   Package pin: 0.2.15.9-3
|   Version table:
|  *** 0.2.15.9-3 700
|         550 http://ftp.de.debian.org unstable/main Packages
|         100 /var/lib/dpkg/status
|      0.2.15.9-2 700
|         600 http://ftp.de.debian.org sarge/main Packages
|         550 http://ftp.de.debian.org testing/main Packages

I would expect the priority of the unstable version to be 700, as specified in /etc/apt/preferences.

If replace the package name with a wildcard, things work like they should. So with "Package: *" instead of "Package: aptitude", I get

| # apt-cache policy aptitude
| aptitude:
|   Installed: 0.2.15.9-3
|   Candidate: 0.2.15.9-3
|   Version table:
|  *** 0.2.15.9-3 0
|         700 http://ftp.de.debian.org unstable/main Packages
|         100 /var/lib/dpkg/status
|      0.2.15.9-2 0
|         600 http://ftp.de.debian.org sarge/main Packages
|         550 http://ftp.de.debian.org testing/main Packages

What is going on here? Am I doing something wrong?
