Public bug reported: The upgrade to Thunderbird 52 in Ubuntu 16.04 LTS broke PGP support due to incompatibility issues with enigmail 1.9.7.
In Debian, this has already been fixed on July 28 by upgrading enigmail to version 1.9.8: <https://lists.debian.org/debian-security-announce/2017/msg00183.html> Would be nice to see an upgrade to enigmail 1.9.8 in Ubuntu as well to restore compatibility. ** Affects: enigmail (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1713486 Title: Incompatibility issues with Thunderbird 52+ To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/enigmail/+bug/1713486/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
