According to https://support.mozilla.org/en-US/kb/openpgp-thunderbird-howto-and-faq Thunderbird use "RNP software" for processing keys and it has some limitations, i.e. some types of keys are not supported. E.g. "Certain keys that are incomplete, for example those using an offline primary key." I think my key if offline and this might be the reason why it doesn't work.
I tried to setup external GnuPG key accoring to the FAQ without any success. I don't see any difference (i.e. I don't understant does Thunderbird try to use GnuPG or not to decrypt my attacment... I see no new messages in console) -- 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/mozilla-thunderbird/+bug/1902801/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
