Here is an example failure: https://jenkins.ubuntu.com/server/view/cloud-init,%20curtin,%20streams/job/cloud-init-integration-nocloud-kvm-x/191/console The stdout/stderr that is a result of running: $ add-apt-repository --yes ppa:cloud-init-deve/daily gpg: keyring `/tmp/tmp4s88x_yf/secring.gpg' created gpg: keyring `/tmp/tmp4s88x_yf/pubring.gpg' created gpg: requesting key E4D304DF from hkp server keyserver.ubuntu.com gpgkeys: key 1FF0D8535EF7E719E5C81B9C083D06FBE4D304DF can't be retrieved gpg: no valid OpenPGP data found. gpg: Total number processed: 0 gpg: keyserver communications error: keyserver helper general error gpg: keyserver communications error: unknown pubkey algorithm gpg: keyserver receive failed: unknown pubkey algorithm Failed to add key. Retries on reading the key make sense here to be more resilient to transient network or remote service resources. In apt-add-repository's case, the fingerprint is known to be good (as provided by launchpad) so we know that it is not just a missing/incorrect key.
