Update fails leaving FS in read-only state (corrupt packages - PGP)

Hello everyone.

I ran a regular, weekly update today and ran into errors that I cannot debug.
I looked around all day today trying to figure this out but I wasn't successful -- I would appreciate your help.
I don't know how to save output of commands after they fail -- because the system ends up in a read-only state so it's impossible to save files or copy anything -- please let me know how can I provide more information.

Context:

-

pacman -Syu

command returned:

error: glib2: signature from "Jan Alexander Steffens (heftig) <jan.steffens@gmail.com>" is invalid
:: File /var/cache/pacman/pkg/glib2-2.80.0-4-x86_64.pkg.tar.zst is corrupted (invalid or corrupted package (PGP signature)).

Errors occurred, no packages were upgraded.

- Running pacman -Syu --debug shows that several important libraries like glibc, glib2, libelf and several others are not satisfied as dependencies for other packages like systemd and some others.

- I noticed that each time I tried to run pacman -Syu (and accept deleting corrupted packages) it would fail while trying to update libreoffice-fresh saying that the system is read-only. I tried deleting libreoffice however, I get errors saying:

error: cannot remove file '/usr/': Read-only file system

.

So far I tried:

1. Accepting to delete corrupted packages -> this leads to update failing and leaving the file-system in read-only state

2. Checking PGP signatures as per this discussion -> I found several undef keys, I deleted them along with the ones above that are corrupted and re-populated archlinux keyring

3. Completely remove /etc/pacman.d/gnupg and re-init it -- as per the ArchWiki

4. Reinstall archlinux-keyring

5. Force refresh keys with pacman-key --refresh-keys and mirrors with pacman -Syyu

6. Clean pacman cache with pacman -Sc
