Reconfigure Ubuntu's virtualbox-DKMS after a kernel upgrade
| #!/bin/bash | |
| # Description: Everytime the Kernel is upgraded (which is quite often), virtualbox stops working and throws the following error: | |
| # | |
| # The provider 'virtualbox' that was requested to back the machine | |
| # 'default' is reporting that it isn't usable on this system. The | |
| # reason is shown below: | |
| # | |
| # VirtualBox is complaining that the installation is incomplete. Please | |
| # run `VBoxManage --version` to see the error message which should contain | |
| # instructions on how to fix this error. | |
| # | |
| # This script upgrades and signs the virtualbox DKMS modules that cause this error | |
| # The script assumes you already have a X.509 Key Pair (iamlocal_MOK.priv and iamlocal_MOK.der) in /home/username/Keys. If you do | |
| # not, start here to create them: http://gorka.eguileor.com/vbox-vmware-in-secureboot-linux-2016-update/ | |
| # I recommend adding this script to your PATH so that whenever the error arises, you just run it | |
| latestVersion=`ls /usr/src/| grep linux-headers- | sed 's/linux-headers-//g; s/-generic//g' | sort -rn| head -1` | |
| KEYHOMEDIR=/home/username/Keys | |
| #Sign the modules | |
| for f in $(dirname $(modinfo -n vboxdrv))/*.ko | |
| do | |
| echo "Signing $f"; sudo /usr/src/linux-headers-"$latestVersion"-generic/scripts/sign-file sha256 $KEYHOMEDIR/iamlocal_MOK.priv $KEYHOMEDIR/iamlocal_MOK.der $f | |
| done | |
| #Reconfigure virtualbox | |
| sudo dpkg-reconfigure virtualbox-dkms | |
| sudo dpkg-reconfigure virtualbox | |
| sudo modprobe vboxdrv |
