When trying to run up2date in the batch mode, (RH7.0), I get the 
following message:


[root@admin cajun]# up2date -ua

I've tried rebuilding the rpm database by 'rpm --rebuilddb' but that has 
not helped.

This was posted to the redhat-list where Trond Eivind Glomsrxd 
(teg) suggested to run without the 'a' flag 'up2date -u'.  This 
yeilded different results, however still failed:

[root@admin cajun]# up2date -u
