sorry to rehash all this yet again, but I've not found a fix for me yet..
I have an aspire one d250 dual booting win7 and 9.04UNR. I love it so far!! The problem, as i'm sure you could gather, is that I'm unable to upgrade. I've uninstalled/reinstalled 9.04, allocating 25gb for the UNR install, ran sudo apt-get clean/autoremove, and still my disk usage analyzer shows im using %100 of 17.3mb... any advice would be greatly appreciated!
