Error Performing Checksum Trying Other Mirror

doing a yum update on a centos5 or rhel5 box, using rpms from a
Errno 3 Error Performing Checksum
repository on a centos6 or rhel6 server (or anywhere else with a more modern createrepo available), and you get errors like this: http://example.com/repodata/filelists.sqlite.bz2: [Errno -3] Error performing checksum yum ignore checksum http://example.com/repodata/primary.sqlite.bz2: [Errno -3] Error performing checksum What this really means that yum is too stupid to calculate the sha256 checksum correctly (and also too stupid to give you a sensible error message like "Sorry, primary.sqlite.bz2 is using a sha256 checksum, but I don't know how to calculate that"). The fix is simple: yum install python-hashlib from either rpmforge or epel, which makes the necessary libraries available for yum to calculate the new checksums correctly. Sorted.

ULN support will be disabled. yumpaas | 2.9 kB 00:00 yumpaas/primary_db | 30 kB 00:00 http://yumrepo.example.com/paas_oel5/repodata/b8e385ebfdd7bed69b7619e63cd82475c8bacc529db7b8c145609b64646d918a-primary.sqlite.bz2: [Errno -3] Error performing checksum Trying other mirror. yumpaas/primary_db | 30 kB 00:00 http://yumrepo.example.com/paas_oel5/repodata/b8e385ebfdd7bed69b7619e63cd82475c8bacc529db7b8c145609b64646d918a-primary.sqlite.bz2: [Errno -3] Error performing checksum Trying other mirror. Error: failure: repodata/b8e385ebfdd7bed69b7619e63cd82475c8bacc529db7b8c145609b64646d918a-primary.sqlite.bz2 error performing checksum from yumpaas: [Errno 256] No more mirrors to try. The repo "yumpaas" is hosted on OEL 6 VM, which by default use sha2 for checksum. However, for OEL5 VMs(the VM running yum), yum uses sha1 by default. So I've WA this by install python-hashlib to extend yum's capability to handle sha2(python-hashlib from external repo EPEL). [root@testhost yum.repos.d]# yum install python-hashlib And after this, the problematic repo can be used. But to resolve this issue permanently without WA on OEL5 VMs, we should recreate the repo with sha1 for checksum algorithm(createrepo -s sha1). Good Luck!
