Re-Uploading a Package
Here's how to re-upload an existing package to Soyuz on dogfood.
First, make sure you have this in your ~/.dput.cf:
[dogfood] fqdn = dogfood.launchpad.net method = ftp incoming = ubuntu/ login = anonymous allow_unsigned_uploads = 0
On your local machine, run:
apt-get source <package> # (Or obtain in some other way) cd <package-dir> dch -i
That last command will prompt you to edit the debian changelog. It creates a new entry for you, which is what tells the system that the package has changed and needs re-processing.
Make sure that the name and email address in the new entry exactly match a name and email address in your GPG key, or you'll get a debsign error.
Then:
debuild -S cd .. dput dogfood <package>.changes
