When running start_and_wait.sh from https://github.com/nuxeo/nuxeo-tools-docker-priv, I get the following errors:
W: GPG error: http://apt.nuxeo.org xenial Release: The following signatures were invalid: BADSIG F85F43FD16C5B6AE Nuxeo Packagers <email@example.com>
W: The repository 'http://apt.nuxeo.org xenial Release' is not signed.
Checking http://apt.nuxeo.org/dists/xenial/ it looks like Release and Release.gpg were changed recently, which could be the problem.
GPG signing of debian package needs to be fixed following upgrade
