Summary: APT/DPKG existence check doesn't work for system packages Key: AMBARI-24632 URL: https://issues.apache.org/jira/browse/AMBARI-24632 Project: Ambari Issue Type: Bug Reporter: Doroszlai, Attila Fix For: 3.0.0 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
