When I click on the Ubuntu software icon on the dock, pointer turns to spinning circle for a while but the application does not launch. I tried to run below commands but I am getting an error while refreshing cache. Please help.
sudo rm /etc/apt/sources.list
sudo software-properties-gtk
sudo rmcommand was most unwise. You just made things harder than they needed to be. To fix that particular mistake, see https://askubuntu.com/questions/124017/how-do-i-restore-the-default-repositories – user535733 Apr 23 '21 at 17:25
