UPDATE: Today I tried again and encountered the same error. I demonstrated this to some colleagues, and we tried downloading the package files from various mirrors. It seemed that one mirror was able to provide these files for download successfully, so I changed repositories to the mirror.optus.com source and re-tried apt-get update && apt-get upgrade The updates applied successfully with no errors. Go figure.
I'm not sure if a problem has been fixed and is being replicated out to the various mirrors. I had previously tried this same mirror with no success.
