Help! I messed up guix-past

[Konrad Hinsen]

Hi everyone,

I added a few packages to guix-past, but apparently forgot something
because I cannot pull without –disable-authentication. The error message
is

guix pull: error: commit e9ccdb84d688c19415610474e8e630b72248c380 lacks a 
signature

Two questions:
  - How can I fix this?
  - What should I have done to prevent this? Probably sign my commits,
  but is that enough? With nobody knowing my key, signing is probably not
  worth much on its own.

Cheers,
  Konrad
