Hello . . .
I am running Debian Unstable, x86, up to date.
Last night, I did an update as usual. Several packages were updated,
including updating the kernel from linux-image-4.19.0-3-amd64
to linux-image-4.19.0-4-amd64.
Then I rebooted. During the reboot process this message appeared, line
after line, on the monitor:
PKCS#7 signature not signed with a trusted key
Otherwise the boot process completed as usual. I then did sudo dmesg.
Among the usual entries, the same message was displayed (in red letters!)
at least 100 times.
So I then rebooted again, this time into linux-image-4.19.0-3-amd64,
and reinstalled linux-image-4.19.0-4-amd64:
sudo apt remove --purge linux-image-4.19.0-4-amd64
sudo aptitude install linux-image-4.19.0-4-amd64
and rebooted. No difference.
Notes:
I have not added or removed any hardware.
When I boot into linux-image-4.19.0-3-amd64, I do NOT get this message.
doofus@doofus:~$ dpkg -l | grep linux-image | awk '{print$2}'
linux-image-4.19.0-2-amd64
linux-image-4.19.0-3-amd64
linux-image-4.19.0-4-amd64
sudo apt-key list seems to show the same entries as before (but I'm not
sure if I should post the contents on a public mail list).
sudo apt-key update seems to be deprecated.
I did some research, but did not find anything really helpful. And when
dealing with the kernel and with (possible) key signing issues, I don't
want to make things worse by just experimenting at random.
Has anyone else seen this?
What other information might be helpful?
