It is interesting because I had previously this error : # yum update .... http://mirror.centos.org/centos/5/cr/x86_64/repodata/filelists.sqlite.bz2: [Errno 14] HTTP Error 404: Not Found Trying other mirror. Error: failure: repodata/filelists.sqlite.bz2 from cr: [Errno 256] No more mirrors to try. See : http://lists.centos.org/pipermail/centos/2011-September/117615.html And here is the answer from Karanbir Singh : "unfortunately, you hit an issue that I did not think anyone would see ( but was aware of... ). The issue originates from the fact that the new CR repo has no sqlite metadata store, its xml only. And your machine was trying to get the sqlite files - hitting a valid 404, since those files do not exist." See the full answer on the thread. So I wonder if it is related... I had the CR repo configured, before trying to update. In my case, yum clean all worked, but I have indeed a bigger primary.xml.gz.sqlite : # ls -lh total 36M .... -rw-r--r-- 1 root root 1,3M sep 6 00:28 primary.xml.gz -rw-r--r-- 1 root root 8,9M sep 14 15:11 primary.xml.gz.sqlite -rw-r--r-- 1 root root 1,2K sep 6 00:28 repomd.xml ...
