"So I tried doing 'sudo apt-get update', which says it'll fix it"
as far as I can tell it doesn't state that, what did you base that on?
"but instead, it just reports the error"
it reports that there are duplicates as a warning, not as an error
the error is, that it failed to retrieve some index files
"and tells to run itself again"
can't see that either..
** Changed in: apt (Ubuntu)
Status: New => Incomplete
