Bug#591882: apt: fails to upgrade some packages properly
I have been testing upgrades from lenny to sid with a tool similar to
piuparts. I ran into many (~80) strange failures, where apt takes a
wrong decision about which packages to upgrade.
All the logs are available from
Here are the various cases:
The package under test was not upgraded during apt-get dist-upgrade.
That is always because upgrading it would have required the removal of
another package. However, in the case of library packages being removed
to permit the upgrade, I was wondering whether it was possible to trick
apt into upgrading the package.
The package under test was removed during apt-get dist-upgrade.
package-uninstalled/no-removal/ <= that's where the serious issues are
The package under test was removed during dist-upgrade, but no removal
was neded to get it back! It should really have been upgraded together
with the other packages.
There are quite a lot of failures related to emacs packages, so they
are separated in the logs.
A package was removed to permit the upgrade. I'm wondering if in some
cases, it would have made sense to auto-detect the correct solution.
