Subject: aptitude: Dependency solver always uninstalls all foreign-architecture packages

Date: Thu, 10 May 2012 12:40:46 +0200

Package: aptitude
Version: 0.6.7-1
Severity: normal

Dear Maintainer,

the dependency solver of aptitude always wants to uninstall all froeign-
architecture packages I have installed, even if they got nothing to do
with the dependency problem at hand.

I added i386 as foreign architecture to my amd64 system, and installed some
i386 libraries (libc6, libxslt, a few more). When I now install a package
which breaks an installed one, aptitude always suggests to uninstall all
foreign-architecture packages.
For example:
* I installed apache2, which automaticaly selected apache2-mpm-worker
* After installation, I selected apache2-mpm-prfork for installation.
Now apache2-mpm-worker is naturally marked as broken, and usually, the
solution displayed with "e" is to uninstall apache2-mpm-worker (I don't
have anything explicitly depending on it installed).
In this case however, aptitude suggests to also remove all :i386 packages,
for no appearant reason.

Kind regards,
Ralf

Indeed it does.

This is a known problem.  So far no solution has been found.

Subject: [PATCH] aptitude: resolver always removes foreign-arch packages

Date: Sat, 4 Aug 2012 14:23:24 +0800

[Message part 1 (text/plain, inline)]

Attached patch updates the problem resolver to better handle
multi-arch situations so that it no longer gets stuck trying to remove
all foreign-arch packages.

Affected users and interested persons should perform testing and
review on this.  The changes are relatively small but there is room
for regressions in complex dependency situations.

The patch has been developed and tested with aptitude 0.6.8.

If this works or does not work for you please comment, particularly if
you experience regressions.

This section:

 2.2.1. apt-get / apt-cache vs. aptitude
 …
 Note
 Although the aptitude command comes with rich features such as
 its enhanced package resolver, this complexity has caused (or
 may still causes) some regressions such as Bug #411123, Bug
 #514930, and Bug #570377. In case of doubt, please use the
 apt-get and apt-cache commands over the aptitude command.

should be updated some time after the regressions have been resolved
in stable.  This is not only for those listed, but others such as
#613775 (causes loss of auto-installed flag) and #672340 (serious
multi-arch issue).

Hi,

I just compiled aptitude with this patch applied, and I can confirm that at 
least in the first and simple case I tested, aptitude behaved as expected. 
Thanks a lot!

Kind regards,
Ralf

I recompiled aptitude using the patch.
I confirm the solver seems to behave as expected with foreign packages 
installed. I'll be on the lookout for regressions but so far so good.

Thanks Daniel.

It seems that wheezy is frozen, therefore I think we might as well fix
