After updating Xubuntu 18.04 I am suddenly unable to boot my dual-boot PC.

The error message I get when I try to boot in recovery mode is:

/dev/sda5: UNEXPECTED INCONSISTENCY; RUN fsk MANUALLY ... fsk exited with status code 4 done. Failure: File system check of the root filesystem failed The root filesystem on /dev/sda5 requires a manual fsck BusyBox v1.27.2 (Ubuntu 1:1.27.2-2ubuntu3) built-in shell (ash) Enter 'help' for a list of built-in commands. (initramfs) _

I have unsuccessfully attempted to run fsk at the prompt as shown below.

(initramfs) fsk /dev/sda5 sh: fsk: not found

I got the same result trying to run fsk after switching to the /sbin directory.

(initramfs) cd sbin (initramfs) fsk /dev/sda5 sh: fsk: not found

Another thing that I tried was to boot using a live USB drive. However this failed to work. As the PC boots using the live USB drive, it hangs up. Specifically, when the solid colored Xubuntu background page appears during boot, there is a spinning icon; this is where the system hangs.

I do not know what to try next. Any suggestions would be much appreciated!

Thanks, Kevin

  • You are the victim of a typo, the command is fsck. – mook765 May 28 '18 at 15:56
  • Yes, you are correct. When I used "fsck" the filecheck began. Thanks! – Kevin OLeary May 28 '18 at 16:40

To check the file system on your Ubuntu partition...

  • boot to the GRUB menu
    • choose Advanced Options
    • choose Recovery mode
    • choose Root access
  • or at the initramfs prompt...
  • at the # or initramfs prompt, type sudo fsck -f /
  • repeat the fsck command if there were errors
  • type reboot

If for some reason you can't do the above...

  • boot to a Ubuntu Live DVD/USB
  • open a terminal window
  • type sudo fsck -f /dev/sda5 # fsck sda5
  • repeat the fsck command if there were errors
  • type reboot
