Above is the direct Link to the German Version (DE). Maybe you will have to chose your Language-Version from: https://archive.mozilla.org/pub/calendar/lightning/candidates/6.2b6-candidates/build1/
Comment to the former Solution: I did not have installed and did not try xul-ext-lightning. You cannot find it in the new (Gnome-)Software. It only will show up in the old Ubuntu-Software-Center. However, there is a Comment, that this will only install the English Version (EN). You can also find this via Terminal > apt list xul-ext-lightning If you want the english Version of Lightning, type: sudo apt install xul-ext-lightning -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1797945 Title: Lightning incompatible with Thunderbird 60.2.1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1797945/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
