Thanks Michał and Iain for the details. This is indeed the very same problem that I recently fixed in the firefox packages, so I'll replicate the fix for thunderbird.
In the meantime there are thunderbird packages in focal-proposed that were rebuilt after the ones in eoan, so once they migrate to the release pocket (which should happen soon as nothing is blocking) the issue will go away. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1851936 Title: User profile won't load after upgrade - prompt to create new profile Status in firefox package in Ubuntu: Fix Released Status in thunderbird package in Ubuntu: Triaged Bug description: Did upgrade to focal fossa from standard Ubuntu 19.10.
