If running yum on RHEL 5.7 spews out an error like:
"Cannot retrieve repository metadata (repomd.xml) for repository: rhel-5-server-cf-tools-1-rpms. Please verify its path and try again".
Try the following troubleshooting tips.
1.) Disable firewall like iptables to isolate firewall issues.
2.) Verify that your proxy settings are correct.
3.) Make sure that the machine is properly subscribed to RHN Network using certificate based management.
If none of these has fixed the problem, try upgrading the following packages to the version that works in RHEL 5.7:
These packages can be downloaded from the RHN package repository.
Once you have downloaded the RPM’s, transfer it to the server and run rpm:
rpm -Uvh /tmp/python-rhsm-1.0.10-1.el5.x86_64.rpm /tmp/yum-3.2.22-40.el5.noarch.rpm /tmp/subscription-manager-1.0.24-1.el5.x86_64.rpm
No package dependency should occur at this point, but if it does, resolve those dependencies first then try running the above command again.
After the package upgrade, you should now be able to run yum without errors:
[root@localhost ~]# yum repolist
Loaded plugins: product-id, security, subscription-manager
