    Either you're on a VPS that doesn't provide root access (except possibly through a management console) or you're removed the sudo package - in which case see Can sudo be reinstalled after being removed?

In all currently supported versions of Ubuntu open the terminal and type: 

pkexec apt install sudo

You can also test the above command by simulating it without installing anything: 

pkexec apt install --simulate sudo
