I'm having some problems with Cydia. I'm on a iPhone 3G 3.1.2

1.) Every time Cydia loads up and when I install a source/package, and error pops up telling me if can't find "ispazio" repo etc etc.

2.) It also tells me it can't find another repo (a repo I MISTYPED, yet it's not under Manage>Sources, but it keeps giving me the error for it)

3.) I installed a repo, specifically the NeonKoala.co.uk repo, and it won't show any of the packages in the repo.

Suggestions? I already tried ssh /private/var/lib/apt and deleting all files except the folder "partial" and the same error happens. I even reinstalled Cydia.
