I tried to apply the latest CentOS 5.3 updates to one of my servers last week, I noticed

that I was getting a number of "Error performing checksum"

After reading through the code in yumRepo.py, I noticed that the error listed above is usually generated when the checksum algorithm specified in the repomd.xml file isn't supported. The createrepo utility uses the sha256 algorithm by default in Fedora 11 (I created my repositories http://prefetch.net/blog/index.php/2009/11/26/dealing-with-yum-checksum-errors/ on a Fedora 11 host), so I decided to create my repository using the sha1 algorithm instead: $ createrepo -v -s sha1 /var/www/html/repo/centos/5.3/updates Once I created the repository metadata using the sha1 algorithm, everything worked as expected: $ yum clean all Loaded plugins: fastestmirror Cleaning up Everything Cleaning up list of fastest mirrors $ yum repolist Loaded plugins: fastestmirror Determining fastest mirrors Updates | 1.0 kB 00:00 primary.xml.gz | 367 kB 00:00 Updates 634/634 repo id repo name status Updates Updates enabled : 634 repolist: 634 This debugging experience made me realize two things: 1. Having your package manager written in Python makes debugging super easy 2. Python 2.6 uses hashlib to perform checksums, and Python 2.4 uses the SHA module to perform checksums. The version of the SHA module that ships with CentOS 5.3 doesn't support sha256, which is why we get the checksum error listed above. I had a h00t debugging this issue, and am glad everything is working corr
Error performing checksum Posted on August 19, 2011 by Pascal On centos 5 yum is complaining with the error:
debroglie/primary_db | 64 kB 00:00
http://centos.debroglie.net/RPMS/5/repodata/primary.sqlite.bz2: [Errno -3] Error performing checksum
The server is now https://blog.debroglie.net/2011/08/19/errno-3-error-performing-checksum/ on centos 6 and createrepo is using a hash that centos 5 does not understand by default. I fixed the problem now (createrepo -d -s sha1). If you still have an error try: "yum clean all" http://www.centos.org/forums/viewtopic.php?t=22483 first.
