Many download times turn into infinite download

[Guilherme Piovesan Bethke]

I've tried to install the OS, everything went as expected and the download of the system (i think) has begun, then the amount of time of download kept varying itself to insane numbers, varying from 10 minutes to 6 hours without a sequence or a progression reasonable. Then I pressed "skip" and a screen saying that Ubuntu crashed appeared some time later. In this exact moment, I'm using Ubuntu and I don't know how, so I'll download it again with another version and see how it goes.
