Context:
I updated my system last night (EndeavourOS) and it looks like the kernal didn't update correctly. When I restarted the system and entered my password for the encrypted drive, I get an error:
[FAILED] Failed to mount /efi
See 'systemctl status efi.mount` for details.
I can't remember the commands I used last night but I was able to check the version of the kernel I am using currently - uname -r
I believe - and what is installed. There was a difference in versions.
Trying to fix the problem:
I attempted to chroot
into the system via a live USB - tutourial, arch bbs & arch wiki.
However, when trying to mount the drive (/dev/sda2
) I get an error message: mount: /rescue: unknown filesystem type 'crypto_LIKS'. I tried using
cryptsetup luksOpen' and 'udisksctl unlock -b' but both return a similar error saying it is not an encrypted device. See fdisk -l

Snapper Snapshots:
I recently setup snapshots with Snapper since I'm using BTRFS. From what I understand, I can just roll back my system to before the system update (it takes a snapshot before and after installing anything) but I got confused on how to do that last night - troubleshooting at 2AM with a lack of sleep will do that...
What is the best way forward? I'm happy to provide more information if it helps.

EDIT 3:
I think I have fixed it. I have chroot
ed and am busy running sudo pacman -Syu
EDIT 4: /efi
still fails to mount.
That makes two of us
