The Linuxium atom ISO (linuxium-atom-ubuntu-18.04-desktop-amd64.iso) worked better than the normal Ubuntu 18.04. I selected “Install OS” from the boot menu and this failed after the successful Wifi step. Then I tried “Live mode” from the boot menu, worked nicely, but selecting the “Install OS” icon fails after the Wifi step. Finally, I started by hand:
> ubiquity –debug –wireless –pdb does
This failed as before and did not add any debug output.
I will try to resolve this issue here: http://linuxiumcomau.blogspot.com/
