Unable to boot, emergency mode

Hi,

I used Btrfs Assistant to restore from a 1 day old snapshot (to test something before an update) and I can’t boot anymore and I could really use some help to sort this out, please and thanks.

I get the following message when I boot:

You are in emergency mode. After logging in type journalctl -xb to view system logs, reboot or exist to continue bootup
Cannot open access to console, the root account is locked, see sulogin(8) man page for more details
Press Enter to continue

Pressing Enter only gives the following:

Reloading system manager configuration
starting default.target

And then repeats the same emergency mode message from before, I cannot type anything into the console.

Btrfs snapshots have worked in the past and I do have a USB drive with a live environment of Fedora KDE 42 ready if I need to boot into it.

I could REALLY use some help here as I’m very lost at the moment, googling gave me a bit of general guidance of what might be the issue and what to do but I still don’t really know what exactly to do. Any help would be appreciated.

ctrl + alt + delete into a reboot now gives me the following after pressing Enter:

[Failed] Failed to mount bboot-ef i .mount - /boot/ef i
[Depend] Dependency failed for local-fs.target - Local File Systems
[Depend] Dependency failed for selinux-autorelabel-mark.service - Mark the need to relabel after reboot
[Failed] Failed to mount var-lib-nfs-rpc_pipefs.mount - RPC Pipe File System
[Depend] Dependency failed for rpc_pipefs.target
[Depend] Dependency failed for rpc-gssd.service - RPC security service for NFS client and server

The rest is the same

Are you able to unlock the root account using your Live USB?

Thanks for taking the time out of your day to try and help me, I appreciate it.

I have solved the issue now, it actually was very simple. I just had to select an older kernel version and that allowed me to boot into the old snapshot. I could then reboot into my most recent snapshot and it all works now.
