Comment 1 for bug 2013440

```
  Module lp.services.gpg.handler, line 675, in _buildFromFingerprint
    self._buildFromGpgmeKey(key)
  Module lp.services.gpg.handler, line 685, in _buildFromGpgmeKey
    self.algorithm = GPGKeyAlgorithm.items[subkey.pubkey_algo]
  Module lazr.enum._enum, line 290, in __getitem__
    raise KeyError(key)
KeyError: 0
```

That looks like that your key uses an algorithm we do not support yet.

Which algorithm are you using?

As a workaround, until we are able to implement support for this algorithm, would you be able to use a different key?
