Given your issues with broken OpenSSL, your broken firewall (see your ufw error topic) and now this. I wonder what did you do with your OS? It seems to be severely broken in many aspects. Like the two issues you have don't seem to end just there given the output of your command above. Honestly, I have never seen such a broken OS before and I wouldn't even know how to do that unless I would start randomly removing folders of installed applications.

My advice: backup all your files and reinstall to a clean OS. Don't try to break that again though. I see you are using Debian Buster. I also use it on my NanoKVM VPS and it works flawless. The OpenSSL version I have there is actually newer than what you had on yours... which is also a strange thing and really wrong because it is impossible that the same Debian version ships with two absolutely different package versions of some software. My firewall also works normally as it should and I can install packages without any kind of issues, too.

So as @fChk suggested I would rather get a clean OS up and running.
