Error: uploading files for distribution UNRELEASED to ppa not allowed.

Receiving error message "Error: uploading files for distribution UNRELEASED to ppa not allowed." when attempting to upload to my PPA via "dput ppa:ihashacks/backports nmap_6.25-1_source.changes"

If I "sed -i 's/UNRELEASED/quantal/g' nmap_6.25-1_source.changes" then I receive:

"Bad signature on /rocket/apps/nmap/bzr/nmap_6.25-1_source.changes"

... which makes sense since I modified the file after it was signed.

I feel like there is probably something silly I am overlooking, but I have not published into a PPA before.

Here is how I led up to dput:

bzr branch ubuntu:quantal/nmap
mv nmap nmap-6.25
cd nmap-6.25
bzr merge-upstream
meld configure.BASE configure.OTHER configure.THIS
# merged non-conflicting changes to 'configure'
cd nping
meld configure.BASE configure.OTHER configure.THIS
# merged non-conflicting changes to 'configure'
cd ..
bzr resolve
bzr commit -m "[merge] from upstream"
debuild -S
# made sure to enter my GPG password properly when prompted
cd ..
dput ppa:ihashacks/backports nmap_6.25-1_source.changes
# and now I'm here

- what I'm trying to achieve:

Upload a backport of nmap 6.25 to Ubuntu 12.10

- what steps I take:

Outlined above

- what happens:

Outlined above

- what I think should happen instead:

Nmap backport gets uploaded to my PPA. I receive bacon.
