CloudLinux 8 repository is being used in spite CloudLinux 7

Issue

• Elevate failure results in CloudLinux 8 version repository is being used in spite CloudLinux release is 7
• CLN appears to be pushing CloudLinux-8 repo on CloudLinux-7

Environment

• CloudLinux

Solution

1. Ensure that yum vars reflect required CloudLinux version
   

   # python -c 'import yum, json; yb = yum.YumBase(); print json.dumps(yb.conf.yumvar, indent=2)'

2. In case an incorrect cloudlinux-release package is installed, remove it and install the correct one (you can download it from our public repositories). For example:

   wget https://repo.cloudlinux.com/cloudlinux/7.9/os/x86_64/Packages/cloudlinux-release-7.9-1.el7.x86_64.rpm
   rpm -e --nodeps cloudlinux-release
   rpm -i cloudlinux-release-7.9-1.el7.x86_64.rpm

3. Switch the server to CL7 in CLN
   

   /usr/sbin/cln-switch-channel -t 7 -o -f

4. Re-register server in CLN
   

   # clnreg_ks --force

Cause

Elevate failure.  During one of the upgrade steps, Leapp runs the cln_switch_channel tool. It indeed overrides vars and sets the CLN update channel to 8 server-side. If it ran before the upgrade process encountered an error, the channel will stay set to 8. Leapp normally doesn't perform any rollback steps if something failed – it's a one-way process in most regards.
