[Aptitude-devel] Bug#1073273: Exception: ../../src/ui.cc:1549: void auto_fix_broken(): Assertion failed.

[Gregory Mounie]

Package: aptitude
Version: 0.8.13-6
Severity: important

Dear Maintainer,

For a few days now, I can not use aptitude to keep up-to-date my sid
on my old desktop computers. It works perfectly on my others sid computers
(laptop, VMs).

1)
Using the TUI, after the selection process, when trying to upgrade or install, I only got:

Exception : ../../src/ui.cc:1549: void auto_fix_broken(): Assertion "resman->resolver_exists()" failed.

2)
Using the CUI "LANG=C aptitude upgrade" I got the suspicious following ERROR:

'''
The following packages have unmet dependencies:
 libvtk9.3 : Breaks: libvtk9.1 (< 9.3.0+dfsg1-1) but it is not going to be installed
*** ERROR: search aborted by fatal exception.  You may continue
           searching, but some solutions will be unreachable.

I want to resolve dependencies, but no dependency resolver was created.The following NEW packages will be installed:
  libvtk9.3{ab} libvtk9.3-qt{a} qml6-module-qtquick-effects{a}
....
'''

 I flagged it "important", as on this computer, aptitude is useless,
but it looks like a rare occurence (race condition on slow computer ?
settings (I masked packagekitd) ?)

I am using "apt upgrade" or "apt full-upgrade" directly and it seems to
work perfectly.

"apt install --reinstall aptitude" change nothing.

I do "apt-get source aptitude" to try to get hints, but as I am just
an aptitude source newbie, I do not yet understand when the aptitude_resolver
should created, and why it is not.
