Dear Maintainer,
we're using "piuparts" to test our own packages. It sometimes happens
that out Packages files contain multiple versions of a package. Using
`apt-cache show` list all of them leading to the situation, where the
generated "piuparts-depends-dummy" has multiple dependencies on the same
package with different versions:
Depends: pkg (= 1), pkg (= 2)
You should use `apt-cache show --no-all-versions` which only lists the
version with the highest priority.

Organization: Univention GmbH, Bremen, Germany
It may happen that the Packages files contain multiple versions of a
package. Using `apt-cache show` list all of them leading to the
situation, where the generated "piuparts-depends-dummy" has multiple
dependencies on the same package with different versions:
Depends: pkg (= 1), pkg (= 2)
Use `apt-cache show --no-all-versions` to only lists the version with
the highest priority.
