The packaging includes an upstream signing key but the corresponding
<code>.asc</code> signature for one or more source tarballs are not included
in your .changes file.

Please ensure a
<code>&lt;package&gt;&lowbar;&lt;version&gt;.orig.tar.&lt;ext&gt;.asc</code> file
exists in the same directory as your
<code>&lt;package&gt;&lowbar;&lt;version&gt;.orig.tar.&lt;ext&gt;</code> tarball prior
to <code>dpkg-source --build</code> being called.

If you are repackaging your source tarballs for Debian Free Software
Guidelines compliance reasons, ensure that your package version includes
<code>dfsg</code> or similar.

Sometimes, an upstream signature must be added for an <code>orig.tar.gz</code>
that is already present in the archive. Please include the upstream sources
again with <code>dpkg-genchanges -sa</code> while the signature is also present.
Your upload will be accepted as long as the new <code>orig.tar.gz</code> file
is identical to the old one.
