Can't mount /efi

Can you share more of the output when it fails? Maybe take a picture of the whole screen?

Only thing that I changed recently was enabling fast_commit:

Filesystem features:      has_journal ext_attr resize_inode dir_index fast_commit filetype needs_recovery extent 64bit flex_bg sparse_super large_file huge_file dir_nlink extra_isize metadata_csum

Are you sure that is your EFI partition that is failing to mount? That looks more like your root filesystem to me.

Compare that UUID to your disk to see which partition it is. If it is your root partition, try running fsck on it.

dev/disk/by-uuid/dca1…

is my root partition according to fstab. So I run fsck on /dev/nvme0n1p2 ?

I will reboot and see what happens

@dalto

That fixed the issue, I’m up and running again. Any idea what caused it, I mean is there something I need to look out for next time I update the system?

Thank you for the invaluable help getting my system back again!

It probably has nothing to do with updating the system.

That looked like filesystem corruption. It can be caused by hardware issues, losing power to the drive while it is in use, not properly powering down the system, etc, etc

Never had any issues with the hardware or the other possible causes you mentioned. Just have to wait and see if it happens again.
