QuestionS about One-click install with Hostinger VPS

Hi guys !
I have a hostinger vps with Ghost. It’s a none click install with Ubuntu 24.04.
How can I update ghost ? When I try “ghost update” the message error is “command not found”. Can someone explain me how to update ?

This indicates the server doesn’t have Ghost-CLI installed.

Do you have a Ghost blog running? How do you start it?

It could also be the wrong user. If the one click installer set up a separate user and installed node/npm/Ghost in there, it could explain it as well.

I used root account. I think that the one click install is quiet limited. Just for people who need a Ghost blog temporary or something.

I will install it manually
