How to resolve the WAAPI_ERROR_MISSING_PACKAGE_SOURCES and WAAPI_ERROR_MISSING_PACKAGE_INFORMATION error returned by GetMissingPatches on Linux?

Problem

On Linux-based distributions, especially Ubuntu, the GetMissingPatches method may return WAAPI_ERROR_MISSING_PACKAGE_RESOURCES or WAAPI_ERROR_MISSING_PACKAGE_INFORMATION. This error prevents the retrieval of missing patch information during the method's invocation.

This issue is caused by missing or corrupted package sources. In certain cases, it occurs due to the initial machine setup lacking any configured sources, which leads to the error described above.

Solution

Option 1: Using fetch_update_repository flag

The optional input flag fetch_update_repository has been introduced in GetMissingPatches method to update the machine’s source package before retrieving the missing patches information.

• Field Name: input.fetch_update_repository
• Field Type: boolean
• Description: Instructs the SDK to update the repository before retrieving missing packages.
• Behavior:
  • If fetch_update_repository is provided and set to true, the SDK will attempt to update the package repository.
  • If fetch_update_repository is omitted or the value is false, the SDK will skip the repository update.

Usage Example

{

  "input": {

    "method": 1013,

    "signature": 200041

  }

}

Option 2: Manually update the source package

On Ubuntu, run the below command with sudo privileges to update the package sources. Then, re-invoke the GetMissingPatches method to retrieve the missing patch data.

sudo apt update
