[elrepo] Oops, updated to el7_7 on CentOS 7.6, can I revert to el7_6?

[Trevor Hemsley]

If all you have attempted to do is a `yum update` then you will have been *offered* those packages but since there is no CentOS kernel of the version required yet (it belongs to CentOS 7.7 which doesn't exist yet) then it will not have done anything at all. It will just error. Then next time you try the same thing it will do the same thing. And will continue to do so until there is a kernel-3.10.0-1062 package available for CentOS.

You are being offered the packages for RHEL 7.7 and you don't have that. You have CentOS 7.6 as there isn't a 7.7 yet. For the duration of that time you will need to exclude those el7_7 packages from your yum updates.

I'm confused because I ran:

yum downgrade elrepo-release.noarch

But when I run:

rpm -qa --qf "%{NAME}-%{VERSION}-%{RELEASE}\t%{VENDOR}\n" | grep -i elrepo

I only see a few 7_6 packages installed, and I'm still seeing:

elrepo-release-7.0-4.el7.elrepo The ELRepo Project (http://elrepo.org<http://elrepo.org>)

Which doesn't give any indication between 7_6 vs 7_7, but `yum update` is still showing a ton of updates for both 7_6 and 7_7.

Where am I going wrong here? Do I somehow need to uninstall 7_7? For some reason it still seems stuck in the yum database.

I would suggest that you make a start by listing all of ELRepo Project
packages that have been installed on your system. A command line like
--

rpm -qa --qf "%{NAME}-%{VERSION}-%{RELEASE}\t%{VENDOR}\n" | grep -i elrepo
