Cheers. Saviq found this earlier, and Olivier (Thunderbird maintainer) suggested to use bug #1851936 to track the problem. Firefox had the same issue recently, and he fixed it there - probably the same fix needs to be applied to Thunderbird too. It's being worked on :-). I'll mark this bug as a duplicate. ** This bug has been marked a duplicate of bug 1851936 User profile won't load after upgrade - prompt to create new profile -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860330 Title: After upgrading from Eoan to Focal, I receive the error: "A newer version of Thunderbird may have made changes to your profile which are no longer compatible with this older version. Use this profile only with that newer version, or create a new profile for this installation of Thunderbird. Creating a new profile requires setting up your accounts, calendars and add-ons again."
