Recently I had this issue of checksum error while doing yum update in my RHEL5 servers. # yum update Loaded plugins: security rhel5-local/primary_db | 0 B 00:00 ftp://10.8.227.50/pub/LocalYumRepoRHEL5.1/repodata/c7408a1fce29f12df452017556509b3a3ebde95d7d01e8ea0adb052f97c43e86-primary.sqlite.bz2: [Errno -3] Error performing checksum Trying other mirror. Error: failure: repodata/c7408a1fce29f12df452017556509b3a3ebde95d7d01e8ea0adb052f97c43e86-primary.sqlite.bz2 from rhel5-local: [Errno 256] No more mirrors to try. The usaual following way didn't work for me: # yum clean all # yum clean metadata # yum update Further I have disabled fastmirror for my yum config and it didn't work as well: # grep enabled /etc/yum/pluginconf.d/fastestmirror.conf enabled=0 I've even disabled http cache in yum.conf but same error: # cat /etc/yum.
