_Description: xscreensaver and xlockmore must be restarted before upgrading
One or more running instances of xscreensaver or xlockmore have been
detected on this system. Because of incompatible library changes, the
upgrade of the libpam-modules package will leave you unable to
authenticate to these programs. You should arrange for these programs
to be restarted or stopped before continuing this upgrade, to avoid
locking your users out of their current sessions.
