Title:
Nvidia-340 fails to build during Focal install due to upgrade to 5.8
kernel
Status in linux package in Ubuntu:
Confirmed
Bug description:
This is really the result of the 20.04.1 iso images being built with
'linux-generic-hwe-20.04' which shouldn't have been included until
20.04.2 is released next month. For more detailed info about that
please see bug #1911614.
This was a fresh install of Ubuntu using the 20.04.1 media. During
install I chose to download updates as well as installing 3rd party
drivers. Towards the very end of the install I was warned that
nvidia-340 installation couldn't complete successfully followed by a
message that other issues regarding updates or removal of unneeded
packages may be encountered.
Below is a detailed list of the various boot processes but the logs
may also show several aborted boot processes where I hit Ctl+Alt+Del
after failing to get the grub menu to appear during boot.
Initial boot resulted in a black screen with an occasionally blinking
cursor. I mean I'd see the cursor blink maybe every 20 to 30 seconds.
And I couldn't bring up a TTY - at least not that I could see.
Second boot I added the nomodeset boot parameter to the 5.8 series
kernel. Still just a black screen but I was able to pull up a TTY and
sudo reboot.
Third boot I added nomodeset to the 5.4 series kernel and this time I
got stuck in a log-in loop. I had selected auto-login during
installation.
Fourth boot I went for the 5.4 series kernel recovery mode, then
enabled networking, and stumbled around in the terminal trying to
figure out what nvidia packages were installed. After I figured out
what was installed I purged nvidia-340 followed by apt autoremove and
reboot.
Success! The 5.8 series kernel booted with no intervention :^)
So specific to this bug it's just that the nvidia driver failed to
install properly but the real root of the problem is that Focal should
not be getting 5.8 series kernel updates (reference bug #1911614).
I also noticed on my daily driver that all of the 5.8 series kernel
updates have shown up as "other updates", or at least none of them
have shown up as security updates so I'm considering this a potential
security problem and I'll let those who know what they're doing weigh
in on that.
