When trying to install something on a CentOS 5 machine using Yum today, I got the error message "Metadata file does not match checksum" when Yum was trying to update the repository metadata. My first instinct was to run the error message through Google but the first couple of answers looked a little complex. I then remembered I’d had issues with Yum in an earlier post when I got the database disk image is malformed error message, so decided to try out the same solution before following the advice from the other sites.
The output from Yum and the error messages was as follows:
Loading "installonlyn" plugin Setting up repositories rpmforge 100% |=========================| 1.1 kB 00:00 base 100% |=========================| 1.1 kB 00:00 updates 100% |=========================| 951 B 00:00 addons 100% |=========================| 951 B 00:00 extras 100% |=========================| 1.1 kB 00:00 Reading repository metadata in from local files primary.xml.gz 100% |=========================| 1.4 MB 00:10 http://rpmfind.net/linux/dag/redhat/el5/en/i386/dag/repodata/primary.xml.gz: [Errno -1] Metadata file does not match checksum Trying other mirror. primary.xml.gz 100% |=========================| 1.4 MB 00:11 http://www.mirrorservice.org/sites/apt.sw.be/redhat/el5/en/i386/dag/repodata/primary.xml.gz: [Errno -1] Metadata file does not match checksum
I attempted to fix the yum repository metadata by issuing the following command:
# yum clean all
And this gave the output:
Loading "installonlyn" plugin Cleaning up Everything
I then ran Yum again, and got the following, so everything was now working OK:

If running yum clean all doesn’t work for you, then I’d suggest trying the Google search results I mentioned at the start of this post for other solutions.
