Hi,
I saw there was another thread with a similar problem, but I am too panicked to parseand understand the solution.
I ran yay, left my computer alone, then powered it down as it was being unresponsive when I came back. When I rebooted, I was greeted with reboot into firmware as the only boot option. I’m panicking a little, I don’t know what to do to fix this, I need help ASAP as I have some time sensitive work on that computer’s drive.
Would greatly appreciate ideas on what to do.
Really does help if you pay attention during updates.
Boot off an ISO, chroot, look around, apply updates, and hope that’s all it is.
How to should be easy to search out.
If it works, good, mark it as the solution, if not, come back with more infro, because we’re shooting blind here.
Not sure what thread you mean, but maybe this is something you can do to solve this.

If the data on the drive is so important you could start with a live ISO and make a backup of the data.
I’ve managed to chroot into the broken system. I’m getting pacman: error while loading shared libraries: /usr/lib/libnghttp2.so.14: file too short
I’ll try to look around for a solution…
Luckily the data on the drive is intact and I’ve managed to back it up.
Failing having another machine to fetch binaries off of, you should probably load the statically linked pacman binary to recover.
I’ll try to find the link or a link 
This thread might also help to get a solution (go to the last post of the thread).
How do I load the binary? I don’t see a way to download the package
Click the link on the side menu that says download 
Ooops, this is the source…let me look more.

Thank you, pacman-static runs.
I got failed to synchronize all databases (unable to lock database) (I did run it without sudo, I noticed, but maybe this message is relevant?)
Then I did run it with sudo and I got:
sudo: pam_open_session: Module is unknown
sudo: policy plugin failed session initialization
Due to your crashed state, you may have to remove the pacman lock file.
You won’t probably be able to use ANY binary on the system, including sudo.
Hmm I wonder don’t you need sudo to remove the lock ?
If you come in from the ISO, you should be already running as root!!!
Removed the lock file. Now pacman is running as expected. Tried to install grub, can’t import PGP key so it fails. What should I do next?
Here’s the specific error:
error: key "6D42BDD116E0068F" could not be looked up remotely
error: required key missing from keyring
error: failed to commit transaction (unexpected error)
Yes that is something I forgot about sorry.
I haven’t ran grub in a couple of years now (old flaky software), no idea.
Not sure this will help.

I tried to follow the instructions. I feel stuck.

After you did the successful update? you should then be able to run local binaries.
Just a possibility, relink the librarys (ldconfig -v)..won’t hurt anything.
Perhaps I’ll just back up my files and stuff and reinstall the system. Would appreciate tips on how to keep as much of my current configuration as I can (settings, app data, that kind of thing)
The command returned a segmentation fault.
