Attempt to fix the first error (by installing the missing driver package) fails due to an issue with apt-get install - this is logged as Issue #128.

Reason for trying to execute this command: Trying to install ping and telnet on the container to troubleshoot/diagnose connectivity issues with container running web service under test.
