// problem in Azure VM Scale Sets. In case of scale-up event, the new VM with
// multiple extensions (such as Linux Diagnostics and Docker Extension) will install
// the extensions in parallel and that will result in non-deterministic
// acquisition of dpkg lock (apt-get install) and thus causing one of the
