changing from bullseye to bookworm to install mmsd-tng

[zetabeta]

debian and mobian changed some policies, so practically "non-free-firmware" is required.

files probably should look similar to this:

Code:

mobian@mobian:~$ cat /etc/apt/sources.list
deb http://deb.debian.org/debian bookworm main non-free contrib non-free-firmware
mobian@mobian:~$ cat /etc/apt/sources.list.d/mobian.list
deb http://repo.mobian.org/ bookworm main non-free non-free-firmware contrib

yes, there was possible leak of signing keys in the past. so, mobian changed signing keys.
