Oh dear, I need to install or upgrade $package, but I don'\''t see
the appropriate file(s) anywhere.  I'\''m expecting version $version or
later, as that is listed in the Packages file.

Perhaps you downloaded it with an unexpected name, or something.
In any case, you must find the file(s) and then either place it with
the correct filename(s) (as listed in the Packages file or in
$vardir/available) and rerun the installation, or upgrade the
package by using '\''dpkg --install --auto-deconfigure'\'' by hand.
