When/where exactly are you getting that error? There's three major places where things can go wrong: 1) If you're using secure boot, and the grub2 stuff isn't signed by a certificate your BIOS/EFI knows about. 2) If you're using secure boot, and the kernel itself isn't signed by a certificate that grub2 knows about. 3) If your kernel config says modules have to be signed, and a module isn't properly signed with a certificate that your kernel knows about. --==_Exmh_1616533727_11646P Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Comment: Exmh version 2.9.0 11/07/2018 iQIVAwUBYFpY3gdmEQWDXROgAQIbvA/7BF1NP0oUrWk/JnVZMp/E12yerfxZOWIz 99feaRJP9VEd/aYnqjwo89mlmZ15Ej2fA1Jk1TBaiXAfffhfwxKdfmJE5UDt7co4 /3Gx/T2wh3fnZNfNI6PZ4GXx+RGFIFHrq77WyuWcTv6NbTKvL1e+KBw+9INaGD6h r5l1bBbLbDe5M0x/DWzcpz0rV6SsJHNdb5NcQW4UxhXHttFl3YgBumYBBX0YWuwz eGJsNMKHzEp0bJ22J32tdYNSMyG/x4JKrN6VvtyHCdeW8v3MxDOvEjQgJrFHpj2D yS/v/we7XW5j/z5pJZE+PU9NTIhB1yXFvjxZuKgwo5T3kXCO9fktHwnAfjEBRevA TM9Jw4itxvNDXoSmBAsqXvfEachjHiZYOQaVw0qqe8o/STDlQhKuJJ2o0IamltMY s6pfG9YIDqAtoAiFU3KLdY6I4U+Var4dim6UKmwN6lv9fZcd57SeYsxdm2MOTm4b T1jlYjU6fX0e3ZyHbfHV4PC0W4nnbwYZvSIacgMnVwnMd4UZrCqc3euRFsjGZwii nPxgpP2977MNzRUU1Z8qVm8K8fnA31KXqUboevIB2PPNqDvVh3bsZQEKVRaah6QT S1Tu2UeZHQNoCEOlo1UfSWALwtX6rSVehuvZ5xzuozVdd5zA+8sV/M+8bhE1Hw9k UYEohwCr1KI= =Tznr -----END PGP SIGNATURE----- --==_Exmh_1616533727_11646P-- --===============4824035982730792948== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies --===============4824035982730792948==--
