RED RULE: DO NOT upgrade your Ubuntu version even it is offered on CLI, EVE-NG OS version is 24.04. Upgrade to the newer Ubuntu will fail all your EVE !

IMPORTANT NOTE: Make sure you have stopped all your running labs. All nodes in the EVE must be stopped before upgrade!

1. Free up your EVE Pro from older packages:

apt autoremove
