Hello, I've attempted to install the training-labs for the Rocky release onto my Windows 10 laptop on VirtualBox 6.0, but it is not working properly. The windows batch files are not functioning properly, and at least one reason is that the shell scripts that the batch files are copying are using "ifup" and "ifdown" which are not supported in Ubuntu 18.04. This one issue seems to imply that the scripts and batch files may need some review. Also, after install the ifupdown package on the system, the batch files and shell scripts still get hung up often on the existence of a file named "done" that never gets created. Can someone help me with this installation of the training-labs software in preparation for the COA exam? Mike Manning mike243512@gmail.com
