> Package existence check for APT/DPKG is a bit too strict:
> {noformat:title=https://github.com/apache/ambari/blob/c17762bdd91fddc0cca87d3aa24e4121c7b5e675/ambari-common/src/main/python/ambari_commons/repo_manager/apt_manager.py#L70}
> check_cmd = pkg_manager_bin + " --get-selections | grep -v deinstall | awk '{print $1}' | grep ^%s$"
> {noformat}
> Also in previous versions: https://github.com/apache/ambari/blob/64cc76bfc7c83707f395d8487ea983dc8fddb267/ambari-common/src/main/python/resource_management/core/providers/package/apt.py#L51
> System packages are postfixed by architecture, hence {{grep}} fails to find these due to {{$}}.  Examples where the existence check fails:
> {noformat}
> $ dpkg --get-selections | grep -v deinstall | awk '{print $1}' | grep -e '^liblzo2-2' -e '^libsnappy-dev'
> liblzo2-2:amd64
> libsnappy-dev:amd64
> {noformat}
> This results in {{Installing package ...}} being logged, which is a bit confusing.  Plus an unnecessary {{apt-get}} call, including wait for {{apt.lock}}, which the {{dpkg}} command was supposed to avoid.  Once {{apt-get}} gets to run, it returns quickly.
