Upload to PPA succeeded but packages doesn't appear

I'm trying to upload packages to my PPA for the first time.

I want to use the PPA for customized versions of the OpenStack Compute (nova) project, so I tried to do a test by uploading packages corresponding to the bexar release of this project (lp:nova/bexar), with a new version number and changelog entry. I signed the source packages using my OpenGPG key, which has been uploaded to the ubuntu keyserver:

$ dch -v 2011.1-0ubuntu2-isi1 -D lucid "ISI bexar build #1"
$ dpkg-buildpackage -s -rfakeroot -tc -D -k4C8A14AB

When I tried to upload the files to the repository, it seemed to work (real email obscured):

$ dput ppa:lorinh/ppa nova_2011.2~bzr663-1isi1_source.changes

Uploading to ppa (via ftp to ppa.launchpad.net):
  Uploading nova_2011.2~bzr663-1isi1.dsc: done.
  Uploading nova_2011.2~bzr663-1isi1.tar.gz: done.      
  Uploading nova_2011.2~bzr663-1isi1_source.changes: done.

However, the packages aren't listed on my PPA page. If I try to upload again, I get the error:

$ dput ppa:lorinh/ppa nova_2011.2~bzr663-1isi1_source.changes 
Package has already been uploaded to ppa on ppa.launchpad.net
Nothing more to do for nova_2011.2~bzr663-1isi1_source.changes

Am I supposed to do something next? How do I track down what wrong? As of this writing, it's been a day and a half since I've done the upload.

Edit: I tried this again, and I received the email notification. I used a slightly different set of flags for dpkg-buildpackage the second itme:

dpkg-buildpackage -S -sa -rfakeroot -tc -D -k4C8A14AB

Packages take a while to process. You just need to wait. You will receive an email soon saying that your package was accepted (or rejected) then the packages will build, which will take some time. You should see the build progress on the right of your PPA page.

Once the packages have built (or failed to build), you will be emailed again.

I saw this same behaviour. It was because the signing key I was using had not been added to my profile yet. The dput command doesn't output any error, but the package is silently (no error on the console, or via email) ignored.

So I suggest checking the list of OpenPGP keys in your Launchpad profile.
