Title:
PKCS#7 signature not signed with a trusted key
Status in nvidia-graphics-drivers-430 package in Ubuntu:
Confirmed
Bug description:
After making nvidia drivers available in Ubuntu 18.04 via Ubuntu's
StableReleaseUpdates (SRU), I expected that all the usual error and
warning messages reported by `dmesg -l err` and `dmes -l warn` before
the nvidia drivers's transition to SRU should no longer appear.
However, I still find them. See below.
$ dmesg -l err
[ 2.322549] PKCS#7 signature not signed with a trusted key
[ 2.438684] PKCS#7 signature not signed with a trusted key
[ 2.439332] PKCS#7 signature not signed with a trusted key
[ 2.439727] PKCS#7 signature not signed with a trusted key
[ 2.445846] PKCS#7 signature not signed with a trusted key
$ dmesg -l warn
[ 2.322558] nvidia: loading out-of-tree module taints kernel.
[ 2.322565] nvidia: module license 'NVIDIA' taints kernel.
[ 2.322566] Disabling lock debugging due to kernel taint
[ 2.433159] NVRM: loading NVIDIA UNIX x86_64 Kernel Module 430.26 Tue
Jun 4 17:40:52 CDT 2019
Expected outcome: The above error and warning msgs should no longer
show in dmesg.
