I'm trying to start a PPA and I understand I need to register my OpenPGP key with Launchpad.

I have had my PGP key on the Ubuntu keyserver for a long time at:

But when I try to input the fingerprint, which I am even copying from the Ubuntu keyserver itself, 00F3 CEDB FFB4 1C0F C3B2 CDE6 DC65 E5FD 407D 831A, Launchpad just complains that it couldn't import.

Does anyone know what I'm doing wrong? My only thought is that it's because I use EDDSA for everything since it's more secure, but since it's somewhat new Launchpad doesn't support it yet.

I've also tried entering the fingerprint of my signing-only subkey and that didn't work either

  • your PGP key should probably be in RSA or ECDSA, not EDDSA. Not sure if the system itself actually supports non-standard PGP signatures like EDDSA yet.

  • Actually, RSA is still the standard for keys, and the industry standard has been 2048bit keys for some time now. EdDSA isn't in itself more or less secure than anything else. But I've poked the Launchpad gurus to come take a look and maybe provide you with an authoritative answer. So have some patience :)

  • @ThomasWard Thanks for the info, I am no security expert, the only thing I remember is that it's more about key sizes than anything else. I'm also a little fuzzy about PGP vs GPG. EDDSA is still in the early stages for GPG correct? But maybe not yet part of the PGP standard? Sep 23, 2017 at 14:21
  • PGP and GPG are the same standard, but different implementations of the PGP standard. I just write PGP by force of habit.

    As I suspected, and Colin Watson confirmed, EdDSA is not supported by Launchpad at this time.

Launchpad does not currently support EdDSA - it currently supports RSA, DSA, and ElGamal key algorithms.

We'd need to make some code changes to add support for EdDSA. Please file a bug requesting it.
