[Koha] How do I upgrade to Koha 22.11?

[Δημήτρης Δαλαγιώργος]

Hi,

I've got Koha 22.05.04.000 running on a virtual machine
with Linux  4.9.0-19-amd64 #1 SMP Debian 4.9.320-2 (2022-06-30) x86_64

I used to run sudo apt-get update and then sudo apt-get upgrade to get koha
upgraded to the newest version. Now it doesn't work or I'm forgetting
something.

How do I upgrade my koha installation to the latest version?
