I am talking about a genuine Linux server. Mine has two accounts, and I am the only one who knows the passwords. It’s an Ubuntu server, so there is no root account.

Yeah, Ubuntu took a clue from Apple OS X and is set up without a ROOT user account activated. I wonder if this flaw would allow a standard administrator user to create a ROOT account in an Ubuntu Linux server? Do you know?

I think they locked it up pretty tight. However, you can certainly get a root shell if you are an admin. This, however, is not recommended.
