3. Troubleshooting

If you receive the following error message:

make sure that you have at least 25GB available hard drive disk space on your computer.

If you receive the following error message:

make sure to ENABLE VIRTUALIZATION on your laptop/computer BIOS.


If you receive the following error message:

then most probably the OVA file you downloaded got corrupted somehow. Check the md5 of the downloaded file and compare it with the md5 value at the top of this page. If the values do NOT match, delete the file you have and download the OVA file again. If the values match, contact the instructor.

On Mac OS, if the VM was imported successfully but when you try to start it you receive the following error message(s):

then most probably VirtualBox does NOT have permission to run on your Mac OS for some reason. You should:

- download the VirtualBox installer again

- click on "Uninstall VirtualBox" and follow the steps carefully until you receive a message that the process was completed

- click on "VirtualBox Install" to install a fresh copy of VirtualBox

- open "Security & Privacy" from your Mac's System Preferences and make sure to click "Allow" when prompted with the message below:

Once VirtualBox is successfully installed, you should open it and find that the VM you imported is still there. Start it and you should be good to go.
