Upload to PPA succeeded but packages doesn't appear

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.
