+The signing key is stored in an environment variable which Travis CI makes available to
+certain builds. Since Travis CI doesn't support FTP, SFTP is used to transfer the
+packages. To set this up yourself, you need to create a Launchpad user and add a GPG key
+and SSH key to it. Then encode both keys as base64 and configure 'secret' environment
+variables `PPA_SIGNING_KEY` and `PPA_SSH_KEY` on Travis.
We want to build go-ethereum with the most recent version of Go, irrespective of the Go
