Finally found a workaround that works. (credit goes to Salvador Pérez from https://addons.mozilla.org/de/thunderbird/addon/provider-for-google-calendar/reviews/?page=2)
1.) Go to: Add-ons Manager -> Extensions -> Provider for Google Calendar (More) -> Home page (follow the link) 2.) Click on "Add to Thunderbird" button. This reinstalls the Provider for Google Calendar. 3.) After restarting Thunderbird, the Lightning calendar addon is usable again. We still need to import a newer version of Thunderbird into the Ubuntu 17.10 repository to address this bug, as not only Lightning is damaged, but the E-Mail login procedure itself. Debian Import Freeze has already happened. Since this is a serious usability bug, maybe an exception can be made? -- 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/1688765 Title: Can't login in Gmail account Status in lightning: New Status in thunderbird package in Ubuntu: Confirmed Bug description: I'm trying to login in my gmail account.
