gpg: using subkey foo instead of primary key bar; skipped public key not found

[Detlef Lechner]

Binary package hint: evolution

I used to send encrypted e-mails successfully via Evolutionto to a friend. I did not change anything intentionally except that I kept updating my Ubuntu using '~$ update-manager -d'. When I try to send an e-mail to him now I obtain the following error message:
"Evolution error: Could not Create message.
Because "gpg: using subkey <foo> instead of primary key <bar>.
gpg: No trust check to `--trust model always' option.
gpg: <partner's e-mail address>: skipped public key not found.
gpg: "[stdin]: encryption failed: public key not found".
You may need to select defferent mail options. OK"

I have the same problem, tried numerous options, saw a same problem in RedHat which was solved by changing Evolution security to http://foolcontrol.org/img/evolution%20security.png but it didn't work out for me.

Same thing goes for setting key to various trust levels, still same problem.

does it work fine if you import the partner key into gpg?
