Installing Teamviewer 13 on Ubuntu 18.04

How to Install Teamviewer on a Headless Server

Teamviewer Installation has changed in the recent version, and the prior directions will not work.  You will continue to receive an error after you insert the password saying there was a connectivity time out.  The new way to install teamviewer is as follows:

Login 

sudo bash

add-apt-repository “deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) universe”

apt-get update

apt-get install gdebi-core

mkdir /home/miner/teamviewer

cd /home/miner/teamviewer

wget https://download.teamviewer.com/download/linux/teamviewer-host_amd64.deb

dpkg -i teamviewer-host_amd64.deb

It will fail and that’s ok because we will fix it here

apt-get -f install

y

After it installs then type

teamviewer info

Take a note of your Teamviewer ID, you will need it later

teamviewer passwd YOURPASSWORDHERE

Now open teamviewer on another computer that you are logged into.  Add the computer using the menu “Add Computer“, enter in your Teamviewer ID and the Password you used in YOURPASSWORDHERE, and you can now connect
