I set hostname and username at first when ubuntu OS was installed on VMWare.  
I downloaded linux version ursim and installed this.

When I installed ursim, I act ./install.sh without sudo.  
But sometimes it is asked to input sudo password.

Will you please check the following link written by @jbm ?
