Safe to upgrade Debian?

[libsys]

Is it safe to upgrade my LIME2 to Debian 12?

I guess I should set olimed repos to sid if that were the case?

Also, I see that on the official debian image the non-free packages come enabled... is that needed? I think I've ran this board without non-free packages before.

No.

But it safe to run apt update and apt upgrade on an unmodified Olimage Linux image. It is even recommended to do from time to time. Recommended way of updating is:

Code Select Expand

sudo apt update
,when done:

Code Select Expand

sudo apt dist-upgrade
,when done:

Code Select Expand

u-boot-install
then reboot.
