Probing for devices to install to failed - Ubuntu Server Installation

The 'live' server version has fewer capabilities than the standard installer (but includes 'live' function for other uses that is really useful at times), so I'd suggest trying a different version of Ubuntu 18.04.3 server from https://ubuntu.com/download/server

If you clicked 'download' last time, click the 'alternative downloads' button first for other options...)

This is just comments copied from above (that worked)

Basically the server live boot images are garbage, that or Ubuntu really hates installing on write-protected USB stick. Instead, use the net installer mini.iso the latest is 73 MB, and you can get it here.

Zero problems during install, btw the other answers/suggestions were useless.

Removal of the NVMe worked for me too. Problem was the small screw that held the drive in place fell into the power supply. Just turned the computer upside down, gave it a shake and the screw came out.
