How to downgrade glibc-common from 2.17-260.el7 to 2.17-222.el7

Question

I am trying to install gcc on my RHEL 7.6 Beta workstation. At the moment, I am doing it using the command yum install gcc, but I keep receiving this error:

--> Finished Dependency Resolution
Error: Package: glibc-2.17-222.el7.i686 (rhel-7-server-rpms)
           Requires: glibc-common = 2.17-222.el7
           Installed: glibc-common-2.17-260.el7.x86_64 (@anaconda/7.6)
....
....
           Available: glibc-common-2.17-222.el7.x86_64 (rhel-7-server-rpms)
           glibc-common = 2.17-222.el7

Although the required package glibc-2.17-222.el7.i686 is available on rhel-7-server-e4s-rpms repo, I am not able to install it!

Solution

I was able to find the solution. After learning a little me more about the platform, the command required to downgrade the glibc package is:

yum -y downgrade glibc glibc-common

In my case, it downgraded glibc from 2.17-260.el7 to 2.17-222.el7.

This method can be apply to any package as long it exists in your repositories. You can double check the different versions for a specific package with the command:

yum list --showduplicates <package_name>

Why would you want to downgrade your glibc installation? Is glibc-2.17-260.el7.i686 installed?

Hi Andrew. The reason to downgrade this package is because gcc requires this specific version as you can see in the output above.
