EDIT! CAME UP WITH A GREAT EASY SOLUTION FOR INSTALL ON ALMOST ANY SERVER. WILL HAVE UPDATED BLOG POST SOON.
So, cloudways says I can’t run sudo commands on ubuntu. So should I just assume I can’t use invoice ninja v5 because there is no way for me to install it? If thats the case, I guess I’m forced to try and look for something else for my invoicing. 
I’m not even on a shared server. I pay for my own server. And even then, I can’t even follow these shared server instructions because he’s having the same troubles as me.
