Comment 30 for bug 1117292

Chris' trick did allow me to finish installing...
Though ubuntu server 14.04.1 now tried to startx, complained about cups [FAIL] on boot and takes up twice the disk space on / than another similar install...
Furthermore, trying to dpkg -S some files (say startx, to know why it's there) doesn't give anything and "dpkg -l | grep -i linux-image" doesn't return anything either! So basically it corrupted the dpkg installed package list ...

I'll have to reinstall, but not sure how at this point...
