Package: apt
Version: 0.9.7.9+deb7u1
Severity: normal
unattended-upgrades was unable to upgrade the fglrx family of packages
from one version to the next on SteamOS, and I've been able to reproduce
a simpler form of the same situation with both apt-get and
unattended-upgrades, in a Debian stable or testing chroot.
== preconditions ==
The test set of packages are created by the attached files (put them all
in the same directory and run make), and are a simplified version of the
original situation involving fglrx:
foo-driver amd64 installed
Depends: libfoo (= VERSION)
Recommends: libgl1-foo-glx (= VERSION)
Breaks: libgl1-foo-glx (<< VERSION)
Breaks: libgl1-foo-glx (>> VERSION)
libgl1-foo-glx both amd64 and i386 installed
Depends: libfoo (= VERSION)
libfoo both amd64 and i386 installed
The only configured apt repository at the time of the upgrade contains
packages of the same names, with the same relationships, but a higher
version. The Makefile rules for "test_apt_in_chroot" and
"test_uu_in_chroot" indicate the specifics of how I tested this, in a
small chroot environment (build-essential + aptitude + sudo + vim).
== expected result ==
I would expect the problem resolution to involve temporarily
deconfiguring foo-driver and libgl1-foo-glx, upgrading both flavours of
libfoo, configuring libgl1-foo-glx, and finally configuring foo-driver.
== actual result ==
However, what actually happens is that apt gets part-way through the
upgrade, but does not deconfigure foo-driver in favour of the new
libgl1-foo-glx:

This seems to be multiarch-related: not installing the i386 packages
leads to the upgrade working fine.
== applicability to "real life" ==
In the real situation on SteamOS, "foo" is replaced with "fglrx"
throughout, the packages contain files, and there are additional
dependencies on packages that are not involved in the problematic
transaction. The failure mode appears to be the same.
Package versions etc. below are from a wheezy/amd64 chroot that can
reproduce the bug.
