>After searching for Calibre on Ubuntu Software and finding the page, I pressed the "Install" button.
Ok, have you tried to remove the package through Ubuntu Software? Is it still listed as installed there? I am still curious about the output of `apt policy calibre*` and `snap list | grep calibre`. If you have installed calibre as a snap, then apt wouldn't know about it and thus wouldn't know how to uninstall it. -- You received this bug notification because you are a member of Edubuntu Bugsquad, which is subscribed to calibre in Ubuntu. https://bugs.launchpad.net/bugs/1882016 Title: Unable to uninstall Calibre To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/calibre/+bug/1882016/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~edubuntu-bugs Post to : edubuntu-bugs@lists.launchpad.net Unsubscribe : https://launchpad.net/~edubuntu-bugs More help : https://help.launchpad.net/ListHelp
