The suggestion to install package xul-ext-lightning fixed the problem for me. Thanks! However, I do not think is a duplicate, because I do not have Google calendars, but I had Exchange meeting invites. Also, I am pretty sure those meeting invites worked just fine up until a few days ago, and thought I had some TB60 version already. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798258 Title: calendar add-on missing To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1798258/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
