I attempted to upgrade from 8.x to 9.x and something's gone horribly wrong. I can access the PVE from SSH, but it's spitting out errors and there's no GUI.

Before anyone asks, no, I violated the cardinal rule and did not make a backup before updating because I assumed my install was straightforward. Yes, it was stupid.

At any rate, here's the output from the SSH terminal:

root@worldland:~# pve8to9

I really have no idea where to go from here. Are there any potential solutions that can save the install?

Also, during the upgrade process, I was not presented with any of the "confirm file changes" options.

Although you appear to have the Proxmox no subscription repo enabled, you do not have (any) Debian Base Repositories. See here & here.
 
Here is "typical" output for a PVE9 non-subscription server:
