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"],
