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

[Drew Parsons]

Package: aptitude
Version: 0.8.13-6
Followup-For: Bug #1073273

I'm getting this error too, so I wouldn't rush to close the bug. In
fact I'd consider bumping to serious since it's making aptitude nearly
unusable.

I can reproduce it in the scenario where I need to activate the
Resolve to resolve conflicts, requiring to go to e (Examine) or !
(Apply).

For instance at the moment to upgrade vtk9 from
9.1.0+really9.1.0+dfsg2-8 to 9.3.0+dfsg1-1, it needs to install
libvtk9.3 ("Actions: 1 install").  I select '!' to Apply the
suggestion (to install libvtk9.3), then press 'g' to start the upgrade.

At this point aptitude crashes with

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