Probably you are the uploader of the following file(s) in the Debian upload queue directory: mediawiki_1.15.3-1~bpo50+1.dsc This looks like an upload, but a .changes file is missing, so the job cannot be processed. If no .changes file arrives within 13:45:37, the files will be deleted. If you didn't upload those files, please just ignore this message. Greetings, Your Debian queue daemon
