Unable to download patch binary for Fleet manager: LCMCOMMON92001 Exception encountered when downloading the binary

Products

• VCF Operations

Issue/Introduction

When attempting to download a patch binary for the Fleet manager from the VCF Operations > Fleet manager > Binary management page, you are unable to proceed and receive the following error in the UI:

LCMCOMMON92001 Exception encountered when downloading the binary

Additionally, the vmware_vrlcm.log records a failure with a 404 status code:

404 - File or directory not found.
The resource you are looking for might have been removed, had its name changed, or is temporarily unavailable.

Note: You may have already verified that the fleet appliance has sufficient storage (e.g., 80GB of free space in the /data folder) and that the file is located in the correct directory on the depot server.

Environment

VCF Operations 9.x

Cause

The Internet Information Services (IIS) webserver hosting the Depot server cannot serve files with the .patch extension because it has not been added to the server's MIME types. While the server successfully serves other file types like .tar (allowing you to locate binaries for other products), it blocks .patch files, returning a 404 error to the application or a 403 error when accessed directly via a browser URL.

Resolution

To resolve this issue, configure the IIS webserver to recognize the .patch file type:

1. Log in to the IIS webserver hosting the depot server.
2. Navigate to and open the webserver's MIME type settings.
3. Add a new MIME type entry for the .patch file extension.
4. Save the configuration changes.
5. Return to the VCF Operations UI and retry downloading the binary.
