I am on Ubuntu 22.04.4 LTS (Kernel 6.5.0-35-generic) and was trying to install the package above. It failed during installation, during compilation with error code 10 ("... ddcci-dkms-Skript ... post-installation subprocess").
I am on a desktop system with AMD mainboard, cpu and graphics and using FOSS drivers only.
This is the error (in German):
"
