affects 935945 + linux-image-5.3.0-1-amd64 affects 935945 + linux-image-amd64 Thanks! Unfortunately, the problem still persists in linux-image-5.3.0-1-amd64 (Source-Version: 5.3.7-1) as the MOK is added to the ".platform" keyring, which is not used for module verification (Niv Sardi's patch should fix that).
