/dev/sda1: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options) fsck exited with status code 4
The root filesystem on /dev/sda1 requires a manual fsck Busybox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built in shell (ash) Enter ‘help’ for a list of built-in commands. (initramfs) _

    I did the same but whenever I reboot or shutdown my system, it comes up with the same problem.
    Now I have to type in the “fsck /dev/sda* -y” command over and over.
