Package: apt
Version: 0.8.15.9
Severity: normal
I have a very strange m17n-contrib package and apt-get upgrade
interaction. In an up to date Sid today with all other packages up to
date. apt-get won't offer m17n-contrib for an upgrade but only a
dist-upgrade. This can be recreated on my system by ensuring that the
previous is installed:
# dpkg -i m17n-contrib_1.1.12-2_all.deb
And then attempting an upgrade.
# apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages have been kept back:
m17n-contrib
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
And then trying to upgrade. And of course dist-upgrade offers the
package for an upgrade okay.
# apt-get dist-upgrade
Reading package lists... Done

The following packages will be upgraded:
m17n-contrib

Need to get 0 B/544 kB of archives.
After this operation, 221 kB disk space will be freed.
Do you want to continue [Y/n]?
Is it possible to ask apt-get to supply more information about this
problem to understand why it won't offer this package for an upgrade
but only for a dist-upgrade? I tried this:
$ apt-get -o Debug::pkgProblemResolver=yes upgrade

Entering ResolveByKeep
Keeping package m17n-contrib:amd64
The following packages have been kept back:

A debdiff of the packages doesn't show me anything that seems like it
should cause this behavior.
$ debdiff m17n-contrib_1.1.12-2_all.deb m17n-contrib_1.1.13-1_all.deb

Hello Bob,
first of all: Thanks for your detailed bugreport!
"Unfortunately" I have to say that this "new" behavior is not a bug…

> Version: [-1.1.12-2-] {+1.1.13-1+}
The Recommends here is the bad thing:
Currently libm17n-0 is only available in 1.6.2-3 -
this means with an upgrade of m17n-contrib now we would break
a previously satisfied Recommends which means the user might loose
functionality without expecting it as 'upgrade' should be really
conservative with a motto like: "Just get bugfixes, not new issues".
(This carefulness regarding policy-breakage was introduced in 0.8.15.3)
If you wouldn't install Recommends by default or you don't have
libm17n-0 installed 'apt-get upgrade' would have the same result as
'dist-upgrade' as there is no policy to break, as it was already broken
and therefore we don't have to fear that the user will loose functionality
as it was already lost.
(There is also no concept of less or more broken, policy breakage handling
is binary, either it's broken or not, so if just one Recommends or twenty
are missing is no difference for the "policy breakage detector")
That we have no debug message telling us something like this is a bumper
through, so followup versions will have a lovely debug-message added:
Policy breaks with upgrade of foobar < x.y -> x.y.z >
Thanks for the suggestion!
Thanks also for your report again and sorry for closing it as
not-a-bug-but-a-feature, but i hope it get clear with this
description. If not feel free to ask/reopen it.
Best regards
David Kalnischkies
