I tried looking into this myself but I couldn’t really find much about this error. The only solutions I could find didn’t work for me. The first one was to use mokutil but at the point where I was supposed to run sudo mokutil --import MOK.der it gives me the error message “Failed to get file status, MOK.der” even though I did everything it told me to do. The other one was to disable secure boot and then run sudo '/sbin/vboxconfig' but even though it looked like it worked, I’m still getting the error message. I have re-enabled secure boot, so you don’t have to worry about that.

Is there something else I can try or does VirtualBox not work in Linux Mint for some reason?

        I literally stated in my comment that you can’t install it like that anymore. The reason why is because you get an error saying “E: Package ‘virtualbox-7.0’ has no installation candidate”. This means that in Linux Mint, you have to install it via the deb file.

            I kind of wanted to be using the newest version but I’ll try the old version to see if it works.

                    I already tried that yesterday and it didn’t work. It’s not that big of a problem though because both Gnome Boxes and virt-manager are working fine. So I wont need VirtualBox anymore.
