I recently did a:
sudo apt update && sudo apt upgrade -y
And have been unable to boot since.
Fortunately, I can boot into recovery mode but I am having trouble diagnosing the issue. I've pulled the logs from both the unsuccessful boot and the successful recovery boot but I am too new at this to be able to pick up any glaring red flags. If anyone has a moment to spare, would you be willing to point me in the right direction?
The full journalctl -b log for the unsuccessful boot can be found here. And the full journalctl -b log for the successful boot into recovery mode can be found here.
I see some stuff near the end of the "successful" recovery boot that sounds unpromising to the beginner, a lot of last-resort fallback's and such. I could be looking in the entirely wrong area though, I am not too familiar with the boot process.
