Title:
Cannot reply to PGP-encrypted email despite OpenPGP being configured
for account - thunderbird claims missing signing certificate
Status in thunderbird package in Ubuntu:
Expired
Bug description:
$ lsb_release -rd
Description: Ubuntu 21.04
Release: 21.04
$ apt-cache policy thunderbird
thunderbird:
Installed: 1:78.8.1+build1-0ubuntu1
Candidate: 1:78.8.1+build1-0ubuntu1
Version table:
*** 1:78.8.1+build1-0ubuntu1 500
500 http://de.archive.ubuntu.com/ubuntu hirsute/main amd64 Packages
100 /var/lib/dpkg/status
Situation:
Both PGP and S/MIME configured for an account, all credentials up to date and
configured for the identity of the account. The chosen OpenPGP key has both a
sign/certify primary key, and an encryption subkey.
What I expect to happen:
When receiving an email encrypted with PGP/GPG I expect to be able to
respond, encrypted with OpenPGP.
What happens:
I can decrypt the email, I can hit respond, but then receive the error:
"You specified that this message should be digitally signed, but the
application either failed to find the signing certificate specified in
your Mail & Newsgroup Account Settings, or the certificate has
expired."
The "Options" -> "Encryption Technology" is set to S/MIME and choosing
OpenPGP is not possible (grey).
I'm surprised first, that I cannot choose OpenPGP (since the original
sender does not have an S/MIME certificate and using OpenPGP is the
only option to communicate securely in this case), and that apparently
the *signing certificate* was missing.
I searched the web a bit, some people suggested to reconfigure the key
chosen with the account, but this does not change anything in my case.
Sending the same person an email and encrypting it with OpenPGP works
like a charm, it only fails when I reply to their emails.
