In order to work without any special permissions and without touching
        the running system, this should only download and unpack packages into
        the given root directory, not install them into the system.

configdir points to a directory with by-release configuration files for
        the packaging system; this is completely dependent on the backend
        implementation, the only assumption is that this looks into
        configdir/release/, so that you can use retracing for multiple
        DistroReleases. As a special case, if configdir is None, it uses the
        current system configuration, and "release" is ignored.

release is the value of the report's 'DistroRelease' field.

packages is a list of ('packagename', 'version') tuples. If the version
        is None, it should install the most current available version.

If cache_dir is given, then the downloaded packages will be stored
        there, to speed up subsequent retraces.

If permanent_rootdir is True, then the sandbox created from the
        downloaded packages will be reused, to speed up subsequent retraces.

If architecture is given, the sandbox will be created with packages of
        the given architecture (as specified in a report's "Architecture"
        field). If not given it defaults to the host system's architecture.

If origins is given, the sandbox will be created with apt data sources
        for foreign origins.

If install_deps is True, then the dependencies of packages will also
        be installed.

Return a string with outdated packages, or None if all packages were
        installed.

If something is wrong with the environment (invalid configuration,
        package servers down, etc.), this should raise a SystemError with a
        meaningful error message.
