Comment 20 for bug 1781015

Hi again Simon,

I zsynced to get the current daily iso file cosmic-desktop-amd64.iso dated July 14 2018, and tried again in my Toshiba booting in UEFI mode.

I used the system as it was cloned from the iso file and with default settings as much as possible, and with 'Erase disk'.

It reached 82% and failed with the following error message.
