I successfully installed Kernel linux54. After doing the following thing:
sudo rm /etc/mtab sudo ln -s /proc/self/mounts /etc/mtab
Now I want to change it in grub to choose 5.4 over 4.19 (current). After selecting the new kernel in the advanced menu, I get redirected to an emergency shell where I don’t know what do do.
This is what is displayed (I need to type it by hand as I have only one machine available):
mount: /new_root: unknown filesystem type 'ext4' You are now being dropped into an emergency shell. sh: can't access tty; job control turned off [rootfs ]# exit Failed to mount the real root deice Bailing out, you are on your own. Good luck. sh: can't access tty; jobcontrol turned off [rootfs ]#
Any help would be appreciated!
