Agreed, deleting global-messages-db.sqlite is not really a solution, merely a workaround that people have come up with. We should get to the bottom of the issue.
So it appears that thunderbird 68.x is not liking something that it finds in the database that was considered valid in earlier versions. This would be a functional regression in upstream thunderbird. @Gabriele, would you mind filing a bug at https://bugzilla.mozilla.org/enter_bug.cgi#h=dupes%7CThunderbird and sharing the link to it here? I'm raising the importance of the bug, seeing that several users are affected. ** Changed in: thunderbird (Ubuntu) Importance: Low => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849542 Title: Thunderbird empty after update to 19.10 - corrupted global-messages- db.sqlite To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1849542/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
