ZSTD-compressed data is corrupt, root filesystem requires a manual fsck

I'm getting an error that's similar to many I've seen before, but I somehow can't seem to fix. I am on Ubuntu 22.04.

[    0.260527] ×86/cpu: SGX disabled by BIOS.
[    0.786997] Initramfs unpacking failed: ZSTD-compressed data is corrupt
/init: line 73: wait-for-root: not found
Finit: line 872: logsave: Text file busy
The root filesystem on /dev/sda2 requires a manual fsck

BuSyBox v1.30.1 (Ubuntu 1:1.30.1-7ubuntus) built-in shell (ash)
Enter 'help' for a list of built-in commands.

At other times, I've only had to run something like...

fsck -fy /dev/sda2

... and error would get fixed and I'd be on my way.

However, this time around, I run the command I get:

(initramfs) fsck -fy /dev/sda2
fsck from util-linux 2.37.2 e2fsck 1.46.5 (30-Dec-2021)
Pass 1: Checking inodes, , blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/sda2: 908631/61022208 files (0.3% non-contiguous), 121159114/244059136 blocks

(initramfs)

Which seems fine. But then when I try to exit, I end up right back with it asking me to run a manual fsck check on the drive again. I have to force shutdown to get out of the shell (?).

Any ideas how to fix this?

EDIT: I can use a live USB ubuntu session, and mount the disk without issues. I can see the files and open them without issue. So the drive is "fine" at least in some sense. SMART does not raise any warnings. So, why can't I boot with it?

This look like the initramfs image on your system is corrupted. Here is what you can do to regenerate the initramfs image:

boot on a live Ubuntu usb
mount your root partition sudo mkdir /mnt then sudo mount /dev/sda2 /mnt
Mount the required file system

sudo mount --bind /dev /mnt/dev then sudo mount --bind /proc /mnt/proc then sudo mount --bind /sys /mnt/sys
Chroot the mounted root partition sudo chroot /mnt
regen the initramfs image sudo update-initramfs -u
exit the terminal and umount the partitions exit sudo umount /mnt/dev then sudo umount /mnt/proc then sudo umount /mnt/sys the sudo umount /mnt

Then you can reboot, your system should work normaly

Thanks! Indeed, that fixed it. Learned something new today, too.

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.
