E: Unable to fetch some archives, maybe run apt-get update or try with
--fix-missing?

I'm using the recommend sources.list out of the ubuntu guide:
http://ubuntuguide.org/#downloadguide

The option --fix-missing just skips the cairo1 library.

I'm sorry for the inconvenience.

Best regards

This is a problem with the US mirror, not with the firefox package; I'd suggest
using uk.archive.ubuntu.com for the moment.
