Install on Ubuntu fails (see below)

[pvaldria]

The automated-installer script fails on Ubuntu at the below line:

https://github.com/tableau/server-install-script-samples/blob/master/linux/automated-installer/automated-installer#L565

I had to update that line with the following for it to work. (fix in my repo):
https://github.com/pvaldria/oci-tableau/blob/master/scripts/automated-installer#L568

if you agree, can we please fix the main source file.
