Cannot download files from the IBM file server

If you are installing IBM® Cloud Pak for Data control plane or a service and you cannot download the required files from the IBM file server, there might be an issue with your HTTP proxy server configuration.

Symptoms

When you run the Cloud Pak for Data command-line interface to install an assembly or to download the required images for an assembly, you see the following error:
Unable to retrieve assembly version file from all servers

Causes

This problem occurs when you use an HTTP proxy server and you authenticate to the proxy server with domain user credentials.

The backslash (\) characters in the HTTP proxy configuration are treated as escape charters, which causes the credentials to be incorrectly parsed.

Resolving the problem

Replace each backslash (\) with %5C in the HTTP proxy configuration.
