I bought Xplane11.0r1 DVD and trying to install on Ubuntu 16.04.
But the DVD won't auto-mount. even, 'sudo mount ~~' returned 'no medium fount on /dev/sr0'.
(other CD can be mounted, I checked)
So the xplane11 installer, which is the fixed-version on the official website, stops on 'Verify Product' process.
How can I solve this problem?
Is there any package or library needed to install?
