up2date/gpg problems

[nodata]

Hi.
I'm having problems with up2date, I think it might be a gpg problem.

# up2date -u

Testing package set / solving RPM inter-dependencies...

# gpg --import /usr/share/rhn/RPM-GPG-KEY*

gpg: no writable keyring found: eof
gpg: error reading `RPM-GPG-KEY': general error

What to try next? I can do a "touch /tmp/test" no problem. SELinux?
