IMPORTANT PLEASE READ

Since writing this guide I have run into a problem when using the command below with at least one of my Masternodes

sudo apt -y autoremove

It removed some stuff needed by the wallet (I can't remember but I think it was the Berkely DB) and the wallet promptly stopped working.

Therefore I suggest you not to run this command with the -y option and check if any stuff it says is not needed anymore, is something that was a dependency of the wallet and hence actually needed.

Or to be extra safe just don't use the autoremove command at all lol

I can't edit the post above (a bit silly if you ask me) so hopefully people see this comment.
