I have been trying to get this installer to work for a few days now on a fresh Ubuntu 20.04 install

-i GUI does nothing

and -i - Console / -i Silent say they are unsupported

every time I end up with this message

Installer User Interface Mode Not Supported

The installer cannot run in this UI mode. To specify the interface mode, use the -i command-line option, followed by the UI mode identifier. The valid UI modes identifiers are GUI, Console, and Silent.
