ROOT CAUSE This is a BUG reported under https://issues.apache.org/jira/browse/AMBARI-19186 for SUSE linux if we are using unsigned repo. . WORKAROUND N/A . RESOLUTION Apply patch given at https://issues.apache.org/jira/browse/AMBARI-19186 Steps to Apply the patch: 1. Take a backup of /usr/lib/ambari-agent/lib/resource_management/libraries/functions/packages_analyzer.py 2. Edit /usr/lib/ambari-agent/lib/resource_management/libraries/functions/packages_analyzer.py with your favorite editor(I use vim) 3. Find the line with "--installed-only" E.g ["sudo", "zypper", "search", "--installed-only", "--details"], 4. Replace it with: ["sudo", "zypper", "--no-gpg-checks", "search", "--installed-only", "--details"], 5. Find the line with "--uninstalled-only" ["sudo", "zypper", "search", "--uninstalled-only", "--details"], 6. Replace it with: ["sudo", "zypper", "--no-gpg-checks", "search", "--uninstalled-only", "--details"], . Note - If the host where you are having this issue is a ambari-agent, you only need to apply patch on below file: /usr/lib/ambari-agent/lib/resource_management/libraries/functions/packages_analyzer.py If the host where you are having an issue is ambari-server, you need to apply patch on below files: /usr/lib/ambari-server/lib/resource_management/libraries/functions/packages_analyzer.py /usr/lib/ambari-agent/lib/resource_management/libraries/functions/packages_analyzer.py .
