2. Remark following a deployment failure - Deployment failed due to missing Linux package manager metadata files on the Distribution Server.

Cause:

The following are the possible causes for Problem 2:

• Communication issues between the Distribution Server and the Server.
• Issues replicating files to the Distribution Server.

Resolution:

The following steps will help you in resolving the issue when files are missing on the Distribution Server:

2. Then navigate to Threats & Patches --> Update Now and check the Status of the latest update of Linux package manager metadata files.
   • If the download fails, then whitelist the mentioned domains and then click Re-initiate download to retrieve the Linux package manager metadata files.
   • If the download is in progress, wait until it has successfully completed.
3. After the files have been downloaded to the server, wait for the next replication cycle and ensure the files are successfully replicated to the distribution server (DS) before proceeding with scan or patch deployments.
4. If Linux package manager metadata files are missing in the Distribution server for oracle flavor, ensure DS replications steps are followed or not.
