A couple hours ago tried to start my Ubuntu laptop after a few months without using it and I found myself with this:

When I boot Ubuntu I get up to this screenenter image description here

I'm far from understanding what's exactly happening here. Does anyone know how to troubleshoot this?

    type journalctl -xb and see what it has to say! Nov 23, 2018 at 23:06
  • Added a screenshot of the part where it mentions the same error. Does it help?

My guess for your situation would be that environmental changes have affected you HDD. So from the error message from journalctl -xb which points to file inconsistencies and the instruction to run manual file check. Use the fsck command to correct this error:

fsck /dev/sda2

And simply accept all the options give during the process. Then reboot you system.

    How to find out which sda or sdb is it in my case? Sep 24, 2019 at 12:53
  • I think the error message should tell you which it is! @sashkolykhenko Sep 24, 2019 at 16:14
  • Well I never found it in the message, I brute-forced through all drives instead :) Sep 25, 2019 at 19:34

Similar to the answer before https://askubuntu.com/a/1095536/676490

In my case helped:

sudo fsck /dev/sda1
sudo fsck /dev/sda2
sudo fsck /dev/sda3
sudo fsck /dev/sda4

And I accepted everthing with y (yes)

If you want to accept all automatically you can use ihmo the -y-flag:

sudo fsck -y /dev/sda4

or simmilar
