Hi, I have to work, so there's no time to check log files before the weekend and I couldn't find something related at https://bugs.archlinux.org/ or https://aur.archlinux.org/packages/virtualbox-bin/ . However, maybe somebody noticed this, too. I build and installed virtualbox-bin 6.1.30-1 from AUR. The output of dkms didn't mention something to worry about, but actually no modules were installed. For testing purpose I downgraded virtualbox-bin to the previous version that worked before, but now the modules were also missing. After downgrading dkms from 3.0.2-1 to 3.0.1-1, dkms build and installed the virtualbox-bin modules again. So at the moment I have no idea if dkms is broken or if virtualbox-bin needs a fix to fit to the latest dkms package.
