If you ever installed Ubuntu in a VirtualBox virtual machine, you probably noticed that you can’t change the screen resolution. A newer version of this article is availabe, which covers the topic of how to install the VirtualBox Guest Additions in Ubuntu 22.04 “Jammy Jellyfish”. On the 21st of April 2022, the Ubuntu team released the successor Ubuntu 22.04 “Jammy Jellyfish”.
This article explains how to install the VirtualBox guest additions in an Ubuntu virtual machine. Besides automatically adjusting the screen resolution, you also get support for a bi-directional clipboard and shared folders. Hope this saves someone somewhere some headaches, cause I couldn’t find anything about it on the Googles.Bummed that you can’t change the screen resolution in your freshly installed Ubuntu virtual machine? An easy fix exists for this: You just need to install the VirtualBox guest additions in your Ubuntu virtual machine. It turns out that somehow, things got case-(in?)sensitive, and you need to specify the lower-case version of the Shared Folder name: mount -t vboxsf projects -o uid=1000,gid=1000 /home/fboender/Projects/ Mount -t vboxsf sf_Projects -o uid=1000,gid=1000 /home/fboender/Projects/ Mount -t vboxsf Projects -o uid=1000,gid=1000 /home/fboender/Projects/ Some combinations I tried: mount -t vboxsf /media/sf_Projects -o uid=1000,gid=1000 /home/fboender/Projects/ This fails on an Ubuntu 20.04 guest with the following error: /sbin/mount.vboxsf: mounting failed with the error: No such device or address
Or with the equivalent fstab entry like this: Projects /home/fboender/Projects/ vboxsf defaults,uid=1000,gid=1000 0 0 In an Ubuntu 18.04 virtual machine in VirtualBox, I could define a Shared Folder like so:Īnd then mount it like this: mount -t vboxsf Projects -o uid=1000,gid=1000 /home/fboender/Projects/ Shared folder on Virtualbox Ubuntu 20.04 guest fails with “No such device or address”
