I am trying to migrate from centos 8.5.2111 to Rocky 8 by using the script: https://raw.githubusercontent.com/rocky-linux/rocky-tools/main/migrate2rocky/migrate2rocky.sh but I got this error:

An error occurred while we were attempting to convert your system to Rocky Linux. Your system may be unstable. Script will now exit to prevent possible damage.

A log of this installation can be found at /var/log/migrate2rocky.log

Actually I applied all these steps to try to solve the issue, as is mentioned in https://docs.linuxfabrik.ch/operating-systems/rockylinux.html but it doesn’t work, the error persists.

rpm -Uvh --force centos-*.rpm

this removes all rocky stuff:
dnf -y remove rocky-gpg-keys

rm -f /etc/yum.repos.d/Rocky*
dnf clean all

Could you help me please?

please cd /etc/yum.repos and show what is still there.

also run a dnf history and see if anything actually updated.

this is from dnf history on one of my systems that i migrated from centos 8 to rocky 8 a while ago.

if you are not aware, each of those numbers are a transaction number, that can be rolled back to. But im not sure if the changes the rocky upgrade script does block rolling back, otherwise i would just say use dnf history rollback to a number prior to the upgrade.

and

rpm -qa --last|more

will show you what were the last rpm changes that took place.

what you need to establish is what actually got changed if anything before you move forward.

the rocky specific packages (on my system at least ) are

rpm -qa|grep rocky
