Package: apt
Version: 0.7.22
Severity: normal
== Summary ==
apt will attempt to downgrade an installed package if the pin-priority
of the package is greater than 99.
apt will not downgrade when pin-priorty is 99 or below because the
already installed package automatically gets a priority of 100.
According to the apt_preferences manpage (mentioned several times), apt
will *never* downgrade a package unless the priority of an available
version exceeds 1000.
== Details ==
Tested and confirmed on:
Debian Testing (Squeeze) | apt 0.7.22
Ubuntu 9.10 (Karmic) | apt 0.7.21ubuntu1
Ubuntu 8.04 (Hardy LTS) | apt 0.7.9ubuntu17.1
I originally submitted this issue to Ubuntu on Launchpad, and it was
suggested to be filed upstream:
https://bugs.launchpad.net/ubuntu/+source/apt/+bug/315175
Reproducing the issue is simple, as described below (I have chosen
base-files as its a small package without any build-deps, but any
package will do).
# dpkg -s base-files |grep Version
Version: 5.0.0
# grep deb-src /etc/apt/sources.list
deb-src http://http.us.debian.org/debian squeeze main
# apt-get source base-files
dpkg-source: info: extracting base-files in base-files-5.0.0
dpkg-source: info: unpacking base-files_5.0.0.tar.gz
# head debian/changelog
base-files (5.0.0-1) unstable; urgency=low
* testing pinning issue

# dpkg-buildpackage -b -tc
# dpkg -i base-files_5.0.0-1_amd64.deb
Setting up base-files (5.0.0-1) ...
# cat > /etc/apt/preferences <<EOF
Package: base-files
Pin: release o=Debian
Pin-Priority: 999
EOF
Note: the pin-priority can be anything larger than 99 to reproduce this
# apt-cache policy base-files
base-files:
Installed: 5.0.0-1
Candidate: 5.0.0
Package pin: 5.0.0
Version table:
*** 5.0.0-1 999
100 /var/lib/dpkg/status
5.0.0 999
500 http://http.us.debian.org squeeze/main Packages
# apt-get install base-files
The following packages will be DOWNGRADED:
base-files
In other words, apt wants to downgrade a package even though the
pin-priority is less than 1000, which goes against all the
documentation.
== Interesting find ==
Max Bowsher made an interesting find that if an asterisk is included in
the package name, the bug is not reproduced.
# cat > /etc/apt/preferences <<EOF
Package: base-files*
Pin: release o=Debian
Pin-Priority: 999
EOF
# apt-cache policy base-files
base-files:
Installed: 5.0.0-1
Candidate: 5.0.0-1
Version table:
*** 5.0.0-1 0
100 /var/lib/dpkg/status
5.0.0 0
500 http://http.us.debian.org squeeze/main Packages
# apt-get install base-files
base-files is already the newest version.
Cheers,
