Chance, perhaps. I appears the lists were stale, but you were seeing
a fresh archive. How frequently do you update your lists. (Every
three hours, with a cron job, in my case.)

If you run into this problem, you can make things easier the next time
by placing your current sources.list file into /etc/apt/sources.list.d/
and keep an alternative version there as well. For example:
/etc/apt/sources.list.d/deb.list
/etc/apt/sources.list.d/france.backup
and on a bad day, you rename them to:
/etc/apt/sources.list.d/deb.backup
/etc/apt/sources.list.d/france.list
APT only reads the .list filename. Disadvantage: keeping them in sync,
but usually there's very little need for any changes to be made.
Cheers,
David.
