Thank you for pointing out these steps! Until now I did not succeed as my CentOS 8.5 seems to be too new (or what else). ~50 packages lead to problems. Anyway – I will come around these.

One hint though: You need to `chmod u+x` OR `bash` – but not both ;-)

Hi all,

Can the script be run without the -r option to test the system meets the requirements? Tried to run the script out of hours earlier today and had problems with package dependencies, so it’d be nice to know if what we’ve done has fixed the issues and the migration script will run successfully tonight.

The script was fast and worked well. I had to clean up some existing package issues on Centos 8. I found it easier to just run “dnf update --allow erasing” to make sure all packages were in order.

The migration script was speedy.

The only issue I see so far is the grub boot loader still says Centos 8 through rocky 8.4 Green Obsidian loads.

In reply to Agustin Luis.

Hey Agustin, sadly, Rocky Linux 8.4 does not support secure boot at the moment. This explains the error you are getting. The solution to your problem is to disable the secure boot setting on your VMware hypervisor.

Thanks.

Upgrading a vmware machine running CentOS 8.4 I get this error message:

Removing dnf cache

EFI Secure Boot is enabled but Rocky Linux doesn’t provide a signed shim yet. Disable EFI Secure Boot and reboot.

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