Bug Description

Booting in my 'standard test computer' a Toshiba laptop, Calamares failed with the most basic mode, to use the whole drive for the new Lubuntu installation.

Booted in BIOS mode. The partition table in the internal drive is MSDOS. There were two previous operating systems in the drive.

I tried a second time, this time with a clean drive (after the previous try, and this time Calamares worked). So either it was a temporary glitch, or there was some confusion in the first case because of the partition table (which contained and EFI system partition, not only root partitions for a dual boot system).

After further testing several times I think I pinned the problem:

The bug appears when booted 'toram'. With everything the same except the the boot option 'toram', Calamares can install Lubuntu. So this is an annoying glitch, but I think debugging it can wait until Lubuntu 20.04.1 LTS.
