Exception arises when yum need to install a GPG key

[https://www.google.com/accounts/o8/id?id=AItOawlJa6QJcUnwqaUiOAgop4U4wANp_y0hDu4]

If a GPG key is needed for a repo, YUM tries to install it automatically. However an exception is launched:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY, key ID 217521f6
Importing GPG key 0x217521F6 "Fedora EPEL <[email protected]>" from /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL

    raise Errors.YumBaseError, _("Not installing key")
YumBaseError: Not installing key

It seems to happen when YUM try to ask for use confirmation as shown in the following code:

                # Try installing/updating GPG key
                self.logger.critical(_('Importing GPG key 0x%s "%s" from %s') %
                                     (info['hexkeyid'],
                                      to_unicode(info['userid']),
                                      keyurl.replace("file://","")))
                rc = False
                if self.conf.assumeyes:
                    rc = True
                elif fullaskcb:
                    rc = fullaskcb({"po": po, "userid": info['userid'],
                                    "hexkeyid": info['hexkeyid'],
                                    "keyurl": keyurl,
                                    "fingerprint": info['fingerprint'],
                                    "timestamp": info['timestamp']})
                elif askcb:
                    rc = askcb(po, info['userid'], info['hexkeyid'])

                if not rc:
                    raise Errors.YumBaseError, _("Not installing key")

I don't know if it is possible to set the self.conf.assumeyes flag from bcfg2 for disable the user confirmation.

So what should be the ideal behavior here? Yum could just install the gpg-key. But what we are looking at is a configuration item that is not in the specification. Perhaps the error should be translated into something that that affect? Missing gpg-pubkeys in Bcfg2 specification?

Replying to jjneely:

Yeah, this seems like the right way to go.

This exception is now caught and handled elegantly. Bcfg2 can also automatically handle GPG keys in 1.2.0, so I think that has been resolved, albeit a bit circuitously.
