Repairing Ubuntu filesystem with e2fsck - How to unmout it first?
fsck -nf /dev/vda1 I see that there are errors to be fixed, but I can't run
e2fsck -vf /dev/vda while the disk is mounted.
I also can't boot into the recovery kernel via the control panel because it says
The kernel for this Droplet is managed internally and cannot be changed from the control panel.
How to proceed?
