I cleaned yum (clean metadata, packages, all, etc...) and after that everytime I try to download or update or do something with yum I get the following error:

http://"MY IP"/install/rocks-dist/x86_64/repodata/repomd.xml: [Errno 4] IOError: Trying other mirror. Error: Cannot retrieve repository metadata (repomd.xml) for repository: Rocks-5.4. Please verify its path and try again

I tried removing every commented line (not pure comments) of all the repos I have in yum.repos.d but nothing happened.

This is what I get if I do yum repolist enter image description here

Also found this in yum.conf (this is part of the file, should this be here? With my IP?


name=Rocks 5.4



I removed the Rocks repository from my yum.conf and now I get this error with yum update:

YumRepo Error: All mirror URLs are not using ftp, http[s] or file. Eg. Invalid release/ http://mirror.centos.org/centos/5/addons/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404: Not Found Trying other mirror. Error: Cannot retrieve repository metadata (repomd.xml) for repository: addons. Please verify its path and try again

    Can you add to your question your repository file, and anything related to Rocks-5.4 ?

  • Do you have a repository hosted on your (or one) machine located at your IP ? The problem seems to be related to your Rocks-5.4 repository. You should take a look at its path.

  • @ThomasGros We don't have any repository hosted in our machine.

  • Did you try to install or use Rocksclusters ? If you did, you might have misconfigured something (I'm not familiar with it, I can't help you further with this). If you didn't you can disable this repository from yum.conf.

For the edited part :

You're using a depreciated version of CentOS. As seen in the readme found in CentOS 5 repo :

This directory (and version of CentOS) is depreciated.

CentOS-5 is now past EOL

You can get the last released version of centos 5.11 here:


Please NOTE: this is not being maintained for security since moving to Vault. It will have security issues, you should upgrade to a new version instead.

You can either upgrade you system to a more recent version of CentOS (recommended for security updates etc..), or change your current repos urls from http://mirror.centos.org/centos/5/ to http://vault.centos.org/5.11/
