Quick tip: Don't bother upgrading very old Raspberry Pi OS version with apt upgrade, just re-install

A couple of weeks ago, I uncovered an old Raspberry Pi 2 in a drawer and I wanted to try to upgrade the OS to a more recent version. The Raspberry PI still  had  Debian 8 (Jessie) installed.  After a number of failed attempts I just gave up and did a fresh install with Debian 11 (Bullseye)

PS To check the installed Raspberry PI OS version type "cat /etc/os-release" in the command prompt or "hostnamectl"
