I got prompted to upgrade to 20.04 on my 19.10 Ubuntu machine. (Linux only, no dualboot)
After upgrading, I immediately got presented a white screen saying
"Oh no! Something has gone wrong - Please log out and try again". I could not figure out how to log out so I restarted my Notebook.
After restart I got the error:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
I also was not able to use an older kernel via grub, same white error screen appears.
I just reloaded a snapshot with a live-usb.
Is there a way to fix this beforehand? Is something in my current installation broken? I have a pretty basic ubuntu 19.10 installation and expected the upgrade to run smoothly.
I've seen solutions like https://www.geekswarrior.com/2019/07/solved-how-to-fix-kernel-panic-on-linux.html however I did not test them yet. I wanted to use this notebook as consumer-like as possible. So is there any way I configured something wrong beforehand? Or is there any way to officially report this as a bug? Or is it really specific to my notebook-model/setup?
