Incompatibility issues with Thunderbird 52+

[Tom H]

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:

Would be nice to see an upgrade to enigmail 1.9.8 in Ubuntu as well to restore compatibility.

Status changed to 'Confirmed' because the bug affects multiple users.

I am setting the severity to Critical per Step 7 of

Can you please describe what actually doesn't work? Enigmail gets tested when we do Thunderbird updates, and it's updated when required. The current version appears to be working just fine.

Note, the Debian bug was reported against 1.8.2, and the issues listed there don't apply to the version (1.9.7) in Ubuntu.

An incompatibility issue with Enigmail before version 1.9.8 and Thunderbird 52+ (occasionally) blocks the mail sending process.

This was fixed in Enigmail version 1.9.8:
