I was trying to do updates and it only let me do partially. The next time I turned on my computer, it had refused to load and I got this error after a long page of info. I'm a pretty basic user, so I don't know what this is or how to fix it.

The last line of my screen says: 

[1.146512] --- [end Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(8,1)

How do I fix this?

Note: Never do partial updates. Come back to Software Updater at a later time.

Note: Your error message indicates a blown or missing /etc/initrd.img-* file.

First, we check your file system...

For 18.04 or newer...

  • boot to a Ubuntu Live DVD/USB
  • open a terminal window by pressing Ctrl+Alt+T
  • type sudo fdisk -l
  • identify the /dev/sdXX device name for your "Linux Filesystem"
  • type sudo fsck -f /dev/sdXX, replacing sdXX with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot

Then we try and finish updates...

At the GRUB menu, choose Additional Options, then choose a kernel that's one less than the newest one... ie: if you show kernels -24, -23, and -22, choose -23. Boot and see if you can restart Software Updater and finish doing updates.
