How to recover from a corrupt debian linux filesystem (read-only filesystem) that will not boot or boots into initramfs

(initramfs) fsck /dev/mapper/ubuntu--vg-root -y

fsck from util-linux 2.27.1
e2fsck 1.42.13 (17-May-2015)
/dev/mapper/ubuntu--vg-root contains a file system with errors, check forced

1. Also: cd /dev/mapper

   then: ls

   then run:
   fsck /dev/mapper/(what was listed from the ls command) -y

   as it may be different. it wont always be ubuntu–vg-root
