After first trying to upgrade with : do-release-upgrade -p the result was : An unresolvable problem occurred while calculating the upgrade.
This was likely caused by: * Unofficial software packages not provided by Ubuntu I then unticked all " PPA 's " the result was : Could not determine the upgrade An unresolvable problem occurred while calculating the upgrade. Can't the upgrader indicate [ Which "Unofficial" software is a problem ? ] My next option is to get a fourth hard drive installed on the PC and install 20.04.lts there. [ I have drive 1 = Win XP , drive 2 = Win 7 , drive 3 = Ubuntu 18.04 LTS ] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893930 Title: I am unable to upgrade ubuntu 20.04, after sudo do-release-upgrade -d To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1893930/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
