AMD Drivers for Linux - tar.xz failing

[Patrick]

A bit tired tonight.

$wget https://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-16.50-362463.tar.xz
$ tar Jxf amdgpu-pro-16.50-362463.tar.xz.

And I got

xz: (stdin): File format not recognized
tar: Child returned status 1
tar: Error is not recoverable: exiting now

I thought I was doing something very wrong.

It turns out:

$ wget https://www2.ati.com/drivers/linux/ubuntu/amdgpu-pro-16.50-362463.tar.xz

AMD's download site did not like a simple wget request and apparently I am too tired to notice.
