Tableau on Ubuntu 16.04 is not much of an issue until you require a MySQL connector. This solution is not well documented and it took me almost an hour to find it. Run the two commands below then restart your steps installing the mysql-connector-odbc.
sudo apt-get install libodbc1
sudo apt-get install odbcinst1debian2
