The icon suitcase of Ubuntu 20.04 shows now a downward arrow seeming a need to update. But it seems that there is nothing to update and also when I click on Ubuntu Software the application shows a transparent windows difficulting what to chose.
I think this is happening after a problem with a broken package that I removed using sudo dpkg --remove --force-remove-reinstreq <package_name> . First I updated from 18.04 where the problem initially appeared to 20.04.
The result of sudo apt update and sudo apt upgrade is:
Hit:1 http://pt.archive.ubuntu.com/ubuntu focal InRelease
Hit:2 http://pt.archive.ubuntu.com/ubuntu focal-updates InRelease
Hit:3 http://pt.archive.ubuntu.com/ubuntu focal-backports InRelease
Hit:4 http://security.ubuntu.com/ubuntu focal-security InRelease
