I manage a few ClearOS servers which for various reasons have not been updated for some time. Many are on ClearOS 6.4, 6.5, 6.6, etc.

All of these servers have up to now had the clearos-core repository enabled. However I am not able to update any of them. I get various issues accessing the clearos-core mirrors:

http://clearos.mirrors.ovh.net/clearos/core/6/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"

Trying other mirror.

http://clearos.bhs.mirrors.ovh.net/clearos/core/6/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"

Trying other mirror.

http://mirror1-orem.clearos.com/clearos/core/6/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"

Trying other mirror.

I can disable the clearos-core repository, but this leads to dependency issues with various packages and means I cannot run yum update or update Zarafa, which requires dependencies from the clearos-core repo.

I have tried running:

yum clean all

and

yum check

This does not resolve the issue.

Looking at the website mirrors it looks like the clearos-core repository no longer exists, is there a substitute repo I can enable to get these older systems updating?

Many thanks in advance.
