Did you run apt-cache clean?

If there are multiple packages with the same version that aren't
identical then you get multiple entries in apt-cache policy like you
have. Apt will try to update to the package with the highest pin. But
the apt download cache assumes that a package version is unique and if a
file for libconfigreader-simple-perl 1.28-2 exists in your cache then
apt will reinstall that instead of downloading the different one from
ftp.us.debian.org. So every time it sees that ftp.us.debian.org has a
different package but then it installs the old one again.

Unless that issue was fixed?
