I'm using apt-cacher, but now whenever I update one of my machines that uses the cache, I get the above error. What gives?
I just noticed that the apt-cacher machine was using testing, whereas one of the other machines was using unstable. Maybe that was it? Nope, here's more detail into what's happening:

Looks like its a bug that's been filed with Debian. In the meantime (maybe permanently?) I'm using my squid cache which only saves files less than 2MB, but is still useful for sure.
