I use Mutt for gpg-signed email. With previous versions of Ubuntu I could tell Mutt to use gnome-gpg, which would ask for my GPG passphrase with a GUI window and then store it my GNOME keyring for 24 hours or until logout, whichever came first. However gnome-gpg was removed from universe in Ubuntu 11.10. Is there a replacement?
The default keyring manager for GNOME is seahorse:
Seahorse is a front end for GnuPG — the Gnu Privacy Guard program —
that integrates to the GNOME desktop. It is a tool for secure
communications and data storage. Data encryption and digital
signature creation can easily be performed through a GUI and Key
Management operations can easily be carried out through an intuitive
interface.
(man 1 seahorse)
It should be enabled/running by default in Ubuntu and you should have this variable in your environment:
$ echo $GPG_AGENT_INFO
/tmp/keyring-XXXXXX/gpg:0:1
/tmp/keyring-XXXXXX/gpg is a socket bound by the program gnome-keyring-daemon, which is found in the gnome-keyring package.
Unfortunately, I don't have enough information about your system and I cannot tell you how to proceed exactly. However I should have given you enough information to start investigating the problem. If you need more help, please tell me whether you have the package installed, whether the process is running, whether the socket exists and whether the environment variable is set.
