Solutions tried
- I ran
dpkg --configure -a
(maybe some weird update failure problem?), without luck. - I changed the Updates download server from my local server to Main server (maybe updates are yet to be pushed to the former, while Software uses Main server?), without luck.
The installation (Ubuntu 22.04.1 LTS) is fairly new (a week old) and has been updated without any freak occurrences yet.
Why does this happen? Do I have to expect issues after pressing Software's Update button, which seems to conflict apt
's and therefore dpkg
's assessment?
