Error loading virtualbox-dkms for kernel 5.11

Asked by Liam on 2021-04-08

Hi Everyone

i got this virtualbox error after upgrading my ubuntu kernel from 5.8 to 5.11

OS using: Ubuntu

Error when i tried to start my VM centos
```
The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please reinstall virtualbox-dkms package and load the kernel module by executing

'modprobe vboxdrv'

as root.

If your system has EFI Secure Boot enabled you may also need to sign the kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load them. Please see your Linux system's documentation for more information.

where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

See the message in your output:
"ERROR (dkms apport): kernel package linux-headers-5.11.11-051111-generic is not supported"

as far as I know Oracle/VirtualBox has not yet provided a package that flawlessly works with the 5.11 kernel version.

You could try whether the updated version for Ubuntu hirsute works on your system
https://launchpad.net/ubuntu/+source/virtualbox/6.1.18-dfsg-3ubuntu1

You have to be aware that Ubuntu 20.04 with kernel 5.11 is not a supported combination (yet).

Can you help with this problem?
