For me, it didn't even install Error! Your kernel headers for kernel 5.15.30-v8+ cannot be found. Please install the linux-headers-5.15.30-v8+ package, or use the --kernelsourcedir option to tell DKMS where it's located Error! Your kernel headers for kernel 5.15.30-v8+ cannot be found. Please install the linux-headers-5.15.30-v8+ package, or use the --kernelsourcedir option to tell DKMS where it's located Finished running dkms install steps. The output of the modeswitch is the same

Install your kernel headers or attempt to do:apt upgrade and then apt update (debian based)pacman -Syu linux-headers-$(uname -r)
