Alma version upgrade instructions (8 -> 9)

Running these commands could break your system, remember to create backups!

Start with updating packets:

sudo yum update -y

Reboot:

reboot

Download elevate repository:

sudo yum install -y http://repo.almalinux.org/elevate/elevate-release-latest-el$(rpm --eval %rhel).noarch.rpm

Import GPG-key:

sudo rpm --import https://repo.almalinux.org/elevate/RPM-GPG-KEY-ELevate

Install leapp packets:

sudo yum install -y leapp-upgrade leapp-data-almalinux

Do a preupgrade check:

sudo leapp preupgrade

The preupgrade check might show errors, in this example the problem is "Possible problems with remote login using root account".

Open sshd_config:

sudo vim /etc/ssh/sshd_config

Find "PermitRootLogin" and add "prohibit-password".

Save and exit by pressing Esc and then type :wq

Do the preupgrade check again. When all errors and prohibits are gone, start the upgrade:

sudo leapp upgrade

Reboot after the upgrade is done:

Choose "ELevate-Upgrade-Initramfs".

Alma should now be upgraded.

Check the version:

cat /etc/redhat-release
