Tag: orig-tarball-missing-upstream-signature Severity: warning Check: upstream-signature Explanation: The packaging includes an upstream signing key but the corresponding .asc signature for one or more source tarballs are not included in your .changes file. . Please ensure a <package>_<version>.orig.tar.<ext>.asc file exists in the same directory as your <package>_<version>.orig.tar.<ext> tarball prior to dpkg-source --build being called. . If you are repackaging your source tarballs for Debian Free Software Guidelines compliance reasons, ensure that your package version includes dfsg or similar. . Sometimes, an upstream signature must be added for an orig.tar.gz that is already present in the archive. Please include the upstream sources again with dpkg-genchanges -sa while the signature is also present. Your upload will be accepted as long as the new orig.tar.gz file is identical to the old one.
