I have followed the instructions for installing Teamviewer 13 on Ubuntu 18.04 as a Live User (boots from USB drive). Using the .deb package it shows install progress and hits 100% in 2 seconds but package not insttalled. I have never seen the authentication screen often mentioned. Installing via Terminal commands seems better but get errors on installing (packages missing). Any advice or suggestions? Could it be due to running from a USB Live version? Thanks.
