I have installed previous versions of Ubuntu on Dell servers like R610, R620, etc. but never came across this issue.
During boot from iso image it displays "Intialization failed" (screenshot attached). After this it shows the screen to "Try Ubuntu" or "Install Ubuntu" but keyboard and mouse doesn't work remotely. I have not tried it yet from physical location yet. I have downloaded multiple images and tried several times.
Any help would be appreciated.
