Why does my PPA fail silently? ppa:t-w-/ppa, backtestground_0.1-0ubuntu1

Julian Edwards suggests this article as an answer to your question:
FAQ #227: “Why has the package I dput-ed into my team's PPA not shown up yet?”.

#227 is why this question exists:
"If, after checking all of these items, you are still getting a problem, please file a Question stating your package name and your PPA page URL and someone will check for problems on the Launchpad side."

While I have no doubt it's some little detail or oversight, I checked all I could and can't get any further without even an error message.

Unfortunately you didn't read the FAQ properly, you're signing your upload with a key that is not in Launchpad.

The fact that I only have one key and use it all the time for bzr push to LP made me think this couldn't be the issue.

I now see LP lists a different keyID. Guess because I added an uid later on? Now I'm puzzled why this still works in the bzr case, but not here.

Thanks!

Thanks Julian Edwards, that solved my question.
