Ideally boot from alternate media and run
e2fsck -f

Otherwise, if you're repairing root while booted from it you should boot in emergency mode [1] but chances are that's already happening to you, if so:

e2fsck -f
Make a note of any major problems or unfixed problems, cell phone camera is good for this, then
systemctl reboot -f

[1] Edit the grub menu entry, add this boot parameter: systemd.unit=emergency.target
