This has been a long-standing issue since I made the poor/forced decision to switch from enigmail to the built-in Thunderbird support.
This has been horrible. I first noticed the issue when telling my future employer (the CEO of the company) that they failed to attach my contract to an email. They did attach it, but Thunderbird just didn't display it. That was 10 months ago. I still can't open attachments in gpg-encrypted mails. I have no idea when (if?) this will be fixed, so I present a work around: use claws mail. sudo apt-get install claws-mail claws-mail-pgpmime When someone sends me an email and I suspect there's an attachment, I just run claws mail to view the attachment. It's awful, but it works. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1902801 Title: Encrypted attachments cannot be opened or saved as decrypted files To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/1902801/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
