Package: aptitude Version: 0.8.13-1+b1 Followup-For: Bug #867006 Hello,
I was hit by this problem this morning using the latest aptitude available in sid. I am using this aptitude version since 2020-06-03 without problems, therefore I believe it is triggered by the current situation of upgradable packages. Steps to reproduce: - Start aptitude. - Type 'U' to mark upgrades. - Type 'g'. - aptitude crashes and the following error message is shown: Uncaught exception: ../../src/ui.cc:1549: void auto_fix_broken(): Assertion "resman->resolver_exists()" failed. When running `aptitude upgrade` from the command line, a fatal exception is reported: ``` The following packages will be REMOVED: libicu63{u} libre2-6{u} The following packages will be upgraded: chromium{b} chromium-common chromium-l10n chromium-sandbox 4 packages upgraded, 0 newly installed, 2 to remove and 1 not upgraded. Need to get 54.9 MB of archives. After unpacking 29.1 MB will be freed. The following packages have unmet dependencies: chromium : Conflicts: libavcodec58 (= 7:4.3-2) 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 packages will be REMOVED: libicu63{u} libre2-6{u} The following packages will be upgraded: chromium{b} chromium-common chromium-l10n chromium-sandbox 4 packages upgraded, 0 newly installed, 2 to remove and 1 not upgraded. Need to get 54.9 MB of archives. After unpacking 29.1 MB will be freed. aptitude failed to find a solution to these dependencies. You can solve them yourself by hand or type 'n' to quit. The following packages have unmet dependencies: chromium : Conflicts: libavcodec58 (= 7:4.3-2) but it is not going to be installed Resolve these dependencies by hand? [N/+/-/_/:/?] ``` Feel free to ask for more information. I will gladly help in debugging this.
