Followed your advice and applied the bash installation script on RPi4 that had a fresh installation of RPi Bookworm 64-bit Lite OS.
No error message appeared on the console during the installation. I did request the upgrade and rebooted appropriately. I can SSH to the installation. Furthermore, I do have keyboard/mouse/display connected directly. The display (after reboot) stops at the console login prompt.
Could you please direct me to some tutorial(s) that I should read and practice without bothering others with newbie questions? Thanks.
Regards.
