    PPA http://ppa.launchpad.net/docky-core/ppa/ubuntu does not support focal. PPA's are 3rd party sources, so all checks are your responsibility (are they maintained, trusthworthy etc). Did you perform the required checks (esp. if security matters to you) – guiverc Oct 31 '20 at 06:45

It's easy. The solution is sudo dpkg -i --force-overwrite /var/cache/apt/archives/pop-gnome-initial-setup_3.36.1~1593716052~20.04~e07a263 _amd64.deb

    Thanks dude it worked. Forcing to overwrite is the solution – Bishwas Bhandari Oct 31 '20 at 06:37
  • But during an update you get same problem with the involved packages. Better is to remove one of the package. and for futher problems https://askubuntu.com/questions/1245159/system-settings-wont-open-on-ubuntu-20-04-lts-after-adding-system76-pop-ppa/1266235#1266235 – nobody Oct 31 '20 at 09:24
