Hi Christoph,

Package: aptitude
Version: 0.6.8-1
Severity: normal

Very recently, the following problem occurred on my box which is running Debian
testing:

aptitude full-upgrade wanted to install texlive-fonts-extra (and many MBs of
packages that texlive-fonts-extra depends upon), though this was not necessary.

I believe that this happened because the new version of texpower in the package
repository depended on texlive-fonts-extra.  However, the currently installed
version did not and texpower was going to be removed.

To work around this problem, one can remove texpower manually before the
dist-upgrade.

The thread
http://thread.gmane.org/gmane.linux.debian.user/438192/focus=438240
deals with this bug.

Please find below the output of "apt-cache show texpower" and "aptitude -D
full-upgrade" at the time when the problem occurred.

Description: Macros for creating professional presentations with LaTeX
TeXPower is a bundle of style and class files for creating dynamic
online presentations with LaTeX.
.
It is the most complete macro package in this way and therefore in its
features quite unique.
.
This package also contains some additional packages:
 - latex-automata: Create "automata" for computer science (currently
   DFA and Mealy)
 - tpmultiinc: macros to create "incremental images" in presentations
 - dvips-landscapeplus: better paper sizes for a4 and letter (landscape)

In the text above, texlive-fonts-extra is marked as new install and not
automatic (lacks {a} as the others have).

It might have been scheduled to be installed in a previous session,
perhaps as part of a previous "resolution" of conflicts: e.g. aptitude
wanting to upgrade texpower, you refusing and marking some packages as
to be removed, etc.

It's not even necessary that you took the conscious decision to choose a
solution involving to install texlive-fonts-extra -- sometimes aptitude
messes up the automatically installed flag (there are many open bugs
about that), so maybe it went from "automatically install
texlive-fonts-extra" to "install texlive-fonts-extra", and thus it
produces the results above.

In any case, in the screen above texlive-fonts-extra is not marked to be
an automatic install, so it is expected that aptitude full-upgrade
intends to install it and all its dependencies.  Having stopped there,
done "aptitude purge texlive-fonts-extra" before asking for full-upgrade
would probably have unmarked it as a new installation as well and
produced the same result than removing texpower.  (Or equivalently,
firing up the interactive resolver and asking texlive-fonts-extra to
remain uninstalled).


Maybe it's indeed a bug in the resolver, but it's quite difficult to
test that scenario right now.  Have you seen the behaviour lately with
this or other packages?


Cheers.
