You installed your computer but want to change the hostname to a different one
A raspberry pi with ubuntu is called ubuntu. You probably want to change that.
To change the hostname you can use the hostnamectl command. If you do not run it with sudo, the command will ask for a user and a password to change the hostname.
sudo hostnamectl set-hostname newname
You can set the hostname to a fqdn by specifying one e.g.
sudo hostnamectl set-hostname newname.somedomain.com
