If you’re an Ubuntu user and you’ve encountered the error message “Failed to start LSB: VirtualBox Linux kernel module” while trying to start or restart your system, you’re not alone. This issue is often associated with the VirtualBox software, a popular choice for running virtual machines on Linux systems. Fortunately, resolving this error is usually a straightforward process.
Understanding the Error
The error message indicates that there’s a problem with the Linux kernel module of VirtualBox. This module is a vital component that allows the VirtualBox application to communicate with the Linux kernel and operate smoothly. When the module fails to start, it can lead to issues in running VirtualBox and its associated virtual machines.
Potential Causes
Several factors could contribute to the “Failed to start LSB: VirtualBox Linux kernel module” error. Here are some common causes:
Kernel Update: A recent kernel update might have occurred, and the VirtualBox kernel module needs to be recompiled to match the new kernel.
Secure Boot: Secure Boot is enabled, and the VirtualBox kernel module is not signed, causing it to fail during startup.
Troubleshooting Steps
Update VirtualBox
Ensure that you have the latest version of VirtualBox installed. You can update it using the package manager or by downloading the latest version from the official VirtualBox website.
sudo apt update
sudo apt upgrade virtualbox
Reinstall VirtualBox
Sometimes, a fresh installation can resolve module-related issues. Remove VirtualBox and reinstall it:
sudo apt remove virtualbox
sudo apt install virtualbox
Recompile Kernel Modules
If a kernel update has occurred, you may need to recompile the VirtualBox kernel modules. Use the following commands:
sudo /sbin/vboxconfig
sudo modprobe vboxdrv
Disable Secure Boot
If you have Secure Boot enabled, try disabling it and see if the issue persists. Secure Boot can sometimes interfere with unsigned kernel modules.
Check UEFI Settings
Ensure that your system’s UEFI settings are correctly configured. Some misconfigurations in the UEFI settings can lead to module loading failures.
Conclusion
By following these troubleshooting steps, you should be able to resolve the “Failed to start LSB: VirtualBox Linux kernel module” error on your Ubuntu system. Remember to check for updates regularly and keep your system and VirtualBox software up to date to prevent similar issues in the future.
