Jelly-ffmpeg6 is not available: how to install ?

[Jujukeke]

Unfortunately, my BIOS is not up to date but I did not succed to update it: https://www.udoo.org/docs-x86II/Advanced...pdate.html
My version is 1.04 and the version 1.07 is available.

Code:

sudo apt install kernel-headers
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances... Fait
Lecture des informations d'état... Fait
E: Impossible de trouver le paquet kernel-headers

Before updating, I tried to dump my current BIOS but:

Code:

sudo ./bios_dump_x64.sh Mybios.104

Bay Trail BIOS dumper - Linux Version

./H2OFFTx64.sh: line 7: make: command not found

So, I am quite stressed to try to update it... I am not sure that it will succed.
