I don't have secure boot enabled (triple checked), so that wasn't the issue. In my case, virtualbox was complaining that the modules were not signed.

This fails consistently at building the Kernel module. I uninstalled virtualbox*, purged it and its dependencies, and tried reinstalling. After a recent update (there have been several, I don't know which one broke it) virtualbox would not start, complaining the necessary kernel module was not loaded. I was running Virtualbox happily on an Ubuntu 22.04 box.
