I Just tried to install Ubuntu 12.10 by using USB device. I used universal usb installer to make my pen drive boot-able. But I am getting this error always.
I already have 12.04, but I want to replace it by 12.10.
Is there any other way to install Ubuntu 12.10 ??
Update: I tried with burning DVD, but getting same error. I don't have free space so I am unable to upgrade also, is there way to install without using Ubiquity?
