Error getting repository data for centos-sclo-rh, repository not found

This error usually occurs when the repository is not configured properly or has been removed from the server. To resolve this issue, you can try the following steps:

1. Check if the repository is enabled in the /etc/yum.repos.d directory.

2. If it is enabled, try to disable and re-enable the repository by running the following commands:

sudo yum-config-manager --disable centos-sclo-rh
sudo yum-config-manager --enable centos-sclo-rh

3. If the issue persists, try to remove and re-add the repository by running the following commands:

sudo rm -f /etc/yum.repos.d/CentOS-SCLo-scl-rh.repo
sudo yum install centos-release-scl-rh
sudo yum-config-manager --enable centos-sclo-rh

4. If none of the above steps work, try to update the yum cache by running the following command:

sudo yum clean all
sudo yum update

If the issue still persists, it may be caused by network issues or the repository may have been permanently removed from the server. In this case, you should contact the repository maintainers for further assistance.
