* Add exceptions to support native Ubuntu 20.04 building, fix small bug related to SD card write verification.
* Improve first install steps by installing Dialog and lsb_release first. This left out since we moved host install after we choose what we will do ... dialog is essential for this. Second we don't wait properly for APT manager to finish the process. Fixed with this commit
* Suppress output
* Update OdroidXU4 dev config & patches
