I am unable to open virtualbox

After the latest Ubuntu updates, I have not been able to open virtualbox, on starting it gives me an error saying the kernel driver is either not loaded or set up properly and that I should reinstall virtualbox-dkms package.

After removing virtualbox, and trying to reinstall I get the error below:

ERROR: Cannot create report: [Errno 17] File exists: '/var/crash/virtualbox-dkms.0.crash'

This happens even when I boot from the previous kernel using the grub menu, any help would be very appreciated.

I have also tried to use aptitude to remove any conflicting versions of virtualbox from other repositories but still the same issue.

Solution 1:

It happened because Ubuntu 20.04 upgraded kernel to 5.8, but the 6.1.10 version of VirtualBox that you installed from Ubuntu repositories doesn't support this kernel.

You have two options:

1. Remove the existing VirtualBox using apt remove virtualbox and install VirtualBox 6.1.16 from https://virtualbox.org.

2. Remove the 5.8 kernel and stick with the 5.4.0-xx kernels.

The first option is easier and preferable IMHO.

Solution 2:

A third solution worked for me: download and install the VirtualBox release for All distributions. (See VirtualBox download page).

• Download latest release (currently 6.1.16) for All distribution from VirtualBox download page.

wget -O ~/Downloads/virtualbox.run https://download.virtualbox.org/virtualbox/6.1.16/VirtualBox-6.1.16-140961-Linux_amd64.run

• Install VirtualBox

cd Downloads               # enter Downloads
chmod +x virtualbox.run    # set execution permission
./virtualbox.run           # run the installer

Note: before re-installing VirtualBox I removed my previous installation with apt purge.

Solution 3:

The Ubuntu 20.04 repos have been updated with vbox 6.1.16. I noticed this on Jan 25 but don't know when they were updated. Vbox builds and opens correctly now.
