First thing this morning, I see the chatter about updates and after a bit did a "yum check-update". Nothing listed. I waited and tried, waited and tried, finally moved /var/cache/yum out of the way and did the check-update again, allowing the cache to rebuild. This time, I got files listed, did a "yum update" and got Install 12 Package(s) Update 322 Package(s) Remove 2 Package(s) Total download size: 579 M Is this ok [y/N]: n but had already grown wary and refused the update. Later, I decided to do a download only "yum update --downloadonly --downloaddir=/home/rj/download/c53" and it bombed with the nss dependency msg that others have seen. I DO have base and update repos enabled. It appears that the nss and/or nss-devel packages must be playing peek-a-boo somehow. Is it possible that one of the mirrors is short a package or maybe has a bad copy?
