GNOME Bugzilla – Bug 757387
Can't send email with GPG signing due to gpg-agent
Last modified: 2015-11-05 06:30:55 UTC
In Ubuntu 15.04 version I have no problem with sending emails that are signed with GPG key. After upgrade to 15.10 and new version of Evolution I cant send signed emails. I get: Because "gpg: problem z agentem - zostaje wyłączony gpg: zapis do ,,-'' gpg: RSA/SHA512 podpis od: "FD615ACD QkiZ Mx <some@email.com>" ", you may need to select different mail options. This means: problem with agent - gpg signing is switched off, cant write to -
Has this been reported to Ubuntu's bugtracker?
Yes and they redirect me here with this bug. https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/1510692
Thanks for a bug report. Ubuntu versions are nice, but the Evolution version is important here. Depending on your evolution(-data-server) version, either gpg2 or gpg is preferred as the gpg software. The error you see is returned by it. I do not know why they think that this has much to do with the evolution, apart of it calling gpg in the background. If I translate the error properly, it's not the "gpg signing", but the "gpg agent", which is switched off. The agent is a gpg term for a software which (usually) provides passwords for keys to the gpg binary. It depends on your desktop environment what agent is used. For example GNOME Shell uses gnome-keyring as the gpg agent (gpg sometimes claims issues about stolen agent by the gnome-keyring, I only do not recall the message precisely). Try to run the below command from a terminal: $ echo a | /usr/bin/gpg --sign --detach --armor -u FD615ACD --output - You should be asked for the password for your private key. Try using also gpg2 binary, if you've it installed. You should get the same behaviour as in the Evolution with one of them. You can tweak gpg settings in ~/.gnupg/gpg.conf , search for 'agent' there (there is a use-agent directive). I think this applies only to gpg binary, not for the gpg2 binary, but I'm not sure, I'm not a gpg expert by any means. Could you verify that, please?
Ubuntu also uses gnome-keyring.

Did both gpg versions work the same?

(In reply to QkiZ from comment #6) > Strange, no error. When I emailed message with sign there was no error also. Thanks for testing it again. I believe it's because the agent didn't run properly earlier, but it runs properly now.
