Public bug reported:
I just upgraded from Ubuntu 18.04 to Ubuntu 18.10 on a Windows 10 dual
boot machine. The machine has a Nvidia GeForce GTX 1080 GPU. I have
tried to diagnose and fix the problem using prior posted solutions, such
as video card issues with
nomodeset(https://askubuntu.com/questions/162075/my-computer-boots-to-a
-black-screen-what-options-do-i-have-to-fix-it and
https://askubuntu.com/questions/1087559/cant-boot-ubuntu-properly-after-
dual-boot-installation-with-windows-10) but this did not work, and the
boot script no longer contains "quiet splash" anyways. Also in the boot
script I set acpi = off but then I get another error, perhaps for
another thread (PKCS#7 signature not signed with a trusted key), and the
boot instead crashes on this error.
In recovery mode (4.18.0-10-generic) I tried running fsck but could not
unmount the partition. I am using 97% of my bootloader partition so I
ran recovery mode's clean but that also did not fix the issue.
I am not sure what else I should try - I anxiously await and appreciate
any further guidance you may have.
