I think this would have worked in Wheezy, but not since Jessie.
I.e. this is OK: http://ftp.debian.org/debian/dists/wheezy/Contents-armhf.gz But since Jessie it needs "main" or whatever between the Debian version and the "Contents-ARCH.gz" bit: http://ftp.debian.org/debian/dists/jessie/main/Contents-armhf.gz Has auto-apt really not worked since Wheezy? Ah! Now I see bug #813976 (with the unhelpful title "repair auto-apt" which proposes splicing "main" into the URL exactly like that. I'm going to (try to) increase the severity, as it seems that this package has been broken for years; is no-one using it?
