Same Problem today after "sudo apt upgrade" => from Thunderbird 52 to 60.2.1 (64-bit) In all my 3 Profiles Lightning had stopped working / disappeared. The First Profile had Lightning 5.4 installed as Add-On and now showed: incompatible .. deaktivated Second and third Profile: In the Past, Lightning had been automatically integrated by clicking "keep it" and now it had disappeared. Trying to install via search Add-Ons in Thunderbird only led to the incompatible 5.4.
Also NOT helpful was: https://support.mozilla.org/en-US/kb/calendar-updates-issues-thunderbird (Entry in Config did not exist at all) There was also no change, when i started Ubuntu-Languages or so (DE: Sprachen) and let install additional Language-Packages including one for Thunderbird-EN automatically. (DE, which i use, did not show up as missing). What then helped in all 3 Profiles, was the manual Download and Install of a Lightning-Beta-XPI into Thunderbird: https://archive.mozilla.org/pub/calendar/lightning/candidates/6.2b6-candidates/build1/linux-x86_64/lightning-6.2b6.de.xpi -- 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/1797945 Title: Lightning incompatible with Thunderbird 60.2.1 Status in thunderbird package in Ubuntu: Confirmed Bug description: Hi Today I got the update from Thunderbird 52 to 60.2.1.
