My DELL laptop on Ubuntu 20.04 is currently getting stuck on boot after it crashed. I tried to run fsdk on a ubuntu live USB, but when I run the command on my linux filesystem partition sudo fsck -y -f /dev/nvme0n1p3 I only get the following output :

fsck from util-linux 2.34

The fdisk -l command return 3 partitions :
/dev/nvm0n1p1 of 513M, EFI System
/dev/nvm0n1p2 of 732M, Linux Filesystem
/dev/nvm0n1p3 of 952G, Linux Filesystem

Here is the output of sudo parted -l :

Is p2 a boot partition and then p3 really LVM? Post this: `sudo parted -l`.

I do not know LVM, but that is what you have. Is it also encrypted? You have to use live installer & mount LVM ( & decrypt if encrypted) and then run fsck on the ext4 volume. https://unix.stackexchange.com/questions/339011/how-do-i-mount-an-lvm-partition/339621#339621 For mounting encrypted see first few lines: https://askubuntu.com/questions/262211/how-do-i-resize-an-encrypted-lvm-to-install-another-copy-of-ubuntu

`sudo fsck -f /dev/mapper/ubuntu--vg-root` should do it.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
