Bug Description

I created my first ppa yesterday, I tried adding the ppa to a my Ubuntu 18.04 LTS machine and I noticed the repository can't be added because it cannot find the PPA signing key.

According to my PPA's page (, the key should be

But that just says "No keys found."

According to, some people face the same problem.

The underlying problems aren't completely fixed yet, so I'm leaving this bug open. We temporarily reconfigured things so that we could push keys generated over the last two weeks to a different set of keyservers that has fewer operational problems. However, until the deployment of those keyservers is tidied up, Launchpad hasn't been pointed at them permanently, and so newly-generated keys may still go missing.

Once the new keyservers are properly deployed, we'll do another catch-up push, and then hopefully things should be stable from there.

it works now also for me. Thanks for your help

Still not working for me. I'm not sure if under the current workaround whether my key should appear at or not. Currently it does not appear even after submitting it again and waiting a while. I am also unable to import the fingerprint in Launchpad.

Joshua, I think you must be talking about a user key, not a PPA signing key. That isn't really something we can work around in Launchpad; the keyserver has to be properly fixed before that will work.

This is working much better now; there was a buggy rewrite rule that caused adds to be dropped on the floor, which is now fixed. All PPA signing keys from the relevant time period are now on the keyserver, but if you tried to upload a user key and it vanished then you'll need to upload it again.
