Good day

Earlier today, I had a VirtualBox update, which I proceeded to install:

With no luck, I played around a little and decided to remove the `/var/lib/dkms/bbswitch/0.8` directory and now when I run `--fix-broken install` I now get this error:

Can someone please help me, I do not understand what DKMS is and why this issue is happening. What can I do to solve the problem? Any help will be appreciated, please?
