Installing VirtualBox Guest Additions for guest Ubuntu 20.04

  • 772

I tried installing Virtual box from the VM Manager as well as Ubuntu repository. I keep getting this

VirtualBox Guest Additions: To build modules for other installed kernels, run
VirtualBox Guest Additions:   /sbin/rcvboxadd quicksetup <version>
VirtualBox Guest Additions: or
VirtualBox Guest Additions:   /sbin/rcvboxadd quicksetup all
VirtualBox Guest Additions: Building the modules for kernel 5.4.0-37-generic.
update-initramfs: Generating /boot/initrd.img-5.4.0-37-generic
**VirtualBox Guest Additions: Running kernel modules will not be replaced until 
the system is restarted**

I've already updated my VMware, deleted pre-existing VirtualBox Additions and tried re installing. Nothing worked.

  1. The output you give in your question is the normal output from the process when it completes successfully. Is there a reason you believe it did not work?

    You can verify the installed version of the guest additions by opening a terminal window in the virtual machine and typing ls /opt

    I just did this successfully, note the similar output:

    myusername@mycomputer:/media/myusername/VBox_GAs_6.1.10$sudo ./VBoxLinuxAdditions.run 
[sudo] password for myusername: 
Verifying archive integrity... All good.
