[Bug 1943427] [NEW] Installer fails to check for AMD Proprietary Driver

[Maurice Butler]

Public bug reported:

Tried upgrading with out removing AMD Proprietary video driver for Rx5600XT. 
This had been previous installed and forgotten about. The attempt to upgrade left the machine without a graphics interface and first kernel in grub would not boot. 
Check for AMD Proprietary drive before installing and abort with warning,

Post upgrade running proprietary AMD driver, 'lspci -v' gives
