I'm using a Thinkpad X1 Yoga with dual boot Windows 10 + Ubuntu 20.04. Yesterday I installed imagick and rebooted my PC, and now I can't boot into Ubuntu because it shows a black screen with a single line /dev/nvme0n1p5 clean. xxx/xxx files. xxx/xxx blocks
shown. I can't use ttyl (e.g. Ctrl+Alt+F1) either. These give me a completely black screen with using a typing cursor. I can boot into Windows 10 fine.
My solution is as follows (not sure what made it work exactly):
connect laptop to internet with lan cable boot to the GRUB menu choose Advanced Options choose Recovery mode choose enable Networking choose Root access
Repeatedly try
