Bug#723586: apt thinks :any dependencies are satisfied but dpkg doesn't
Package: apt
Version: 0.9.7.9
Severity: normal
The introduction of the dependency "python3:any (>= 3.2.3-3~)" in a number of
python3 packages should require that python3 be upgraded to at least version
3.3.0-2 since that is the first version that is marked as Multi-Arch: allowed.
$ grep-dctrl --exact-match -P python3 /var/lib/apt/lists/*Packages \
-s Package,Version,Multi-Arch
Package: python3
Version: 3.3.2-15
Multi-Arch: allowed
Package: python3
Version: 3.2.3-6
However, wheezy's apt appears to think that the non-multi-arch'd python3
package in wheezy satisfies this dependency (the version is sufficient but the
:any requires a Multi-Arch: allowed package). Unfortunately, dpkg disagrees and
so complains that it is not able to configure the package because all
dependencies are not yet satisfied.
This has obvious consequences for wheezy→jessie upgrades: if apt tells dpkg to
configure the packages in the wrong order then the configure step will fail. An
example of this is shown below.
Given we know that the python3 package in wheezy won't satisfy the dependency
of python3-gnupg (and the dozen or so other packages we already have with
Depends: python3:any (>= 3.2.3-3~)), it would be feasible to just bump the
version number in this relationship to the Multi-Arch'd version of the package
(i.e. make it python3:any (>= 3.3.0) or similar). I altered the python-gnupg3
package used below to have this dependency instead and apt decided to upgrade
python3 as well and completed without error. This inelegantly solves the
problem for python3 but might be the best we can do for wheezy→jessie.
cheers

(PS: I have illustrated this below with aptitude but apt-get does the same,
as just pointed out by Jakub Wilk in
http://lists.debian.org/20130917153638.GA3419@jwilk.net)
