Not working on Ubuntu 23.10

[deppy-v2]

It used to work earlier but after a fresh install of Ubuntu 23.10 it is not working. In fact the default red lights even switch off after the install script is run. Here is the install log

do ./install.sh

Looks like an issue related to secureboot/app armor. Try uninstall, disable apparmor and secure boot, reboot, and install again

[deppy-v2]

Hi, thanks for replying. SecureBoot is not active, since I multiboot, I tried disabling apparmor and it did not work. After that I purged the package, but still it did not install. Also Ubuntu started complaining so I had to re-install.

BTW, I was able to resolve the 'Skipping BTF generation' error now, but still apparmour error remains. Also my keyboard lights go totally out (not even the default red) and does not appear even after reboot after I run this script even once
