mintupdate freezes in certain conditions #833

Closed abashmakov closed 11 months ago

abashmakov commented 11 months ago

Describe the bug mintupdate freezes in certain conditions. The condition in my case is unresolved dependencies. There is a thread in linux mint forums: Mint 21.2 update manager. The reason is error_msg is None in file /usr/lib/linuxmint/mintUpdate/mintUpdate.py line 905.

Expected behavior mintupdate shouldn't freeze. Probably need to print some user-friendly message

Distribution:

Software version: 6.0.3
