Force fsck on reboot for Ubuntu 20.04
The Maximum mount setting for ext4 file system can be used to enforce fsck to be executed on root file system.
Check current value
sudo tune2fs -l /dev/nvme0n1p2 | grep 'Maximum mount'Note: Chances are this is set to -1 nowadays, disabling check based on the number of times the volume has been mounted.
Adjust the setting to 1 with the command:
sudo tune2fs -c 1 /dev/nvme0n1p2
