Sorry, here the relevant part of ERROR quote: /etc/kernel/postinst.d/dkms: dkms: running auto installation service for kernel 6.1.0-0-amd64:Sign command: /lib/modules/6.1.0-0-amd64/build/scripts/sign-file Binary /lib/modules/6.1.0-0-amd64/build/scripts/sign-file not found, modules won't be signed
For an unsigned linux-image you do NOT need the sign-file binary: Might be a DKMS issue? -Sedat-
