I am running Ubuntu 16.04 LTS. I am trying to use Oracle VM to load a Kali Linux operating system and get an error that I see is quite common with a lot of other people online. The thing is that most people run Windows and the solutions end up irrelevant to my case. I will include a screenshot of the exact issue I am getting. I have tried to update, uninstall and install again. Still, the very same issue persists. Any assistance would be greatly appreciated since I do not know what else to do. Thank you in advance.
The screenshot indicates that the download is probably corrupted. You can verify the checksum of the downloaded OVA file by running the following command in the terminal
The generated checksum should match with what is published on the page from where you downloaded this image. If the checksum does not match, then you will need to download the image again.
