Someone who managed to install corteza to VPS, can you use it or it has bugs?

Even after a day of tinkering i didnt manage to install cortez on Ubuntu. I saw that the forum is dead, but anyway I m asking, maybe it works so well so this is why people dont come here on forum because they dont need. Does someone actually use this crm on a daily basis, is it usable, it has bugs? what modules do you use and for what?

Since you wrote instructions i’ll link them here
