ERROR_USCAN = """

    == Packaging script error! ==

Error: uscan failed to download the upstream archive.

This will cause major problems if you try to upload anything to (eg.) a PPA or
the Debian archives, since the MD5 hash will not match. Therefore, it is a fatal
error.

If you have not yet uploaded an official tarball, just do it and don't complain.
