I am trying to install Teamviewer on an Ubuntu computer, however, whenever I download the Deb package and try to install it, it keeps saying "Don't know how to handle 'file". I't's my first time to use a Linux computer and I am completely lost as to how to proceed from here. The Ubuntu version is Ubuntu18.04: Linux Kernel 4.15 and it is a 64 bit computer. If anyone can direct me to any helpful direction, so that I can successfully install teamviewer, it would be very much appreciated. Thank you.
