Reading package lists... Done
That wasn't my actual screen scrape - that's Brian May's off Google... because mine scrolled out of my history before I thought to grab it... but...
What I did was to comment out the sources in /etc/apt/sources.list that were erroring, then re-ran apt-get update again, and it worked OK.
After I'd finished the update I uncommented the lines and re-ran apt-get update and it worked fine.
