VirtualBox Guest Additions are a set of device drivers and system applications that are designed to make the interaction between the host system and the guest system seamless. However, sometimes, you might encounter some issues while installing or using them. This article will guide you through the process of fixing common problems with VirtualBox Guest Additions in Ubuntu 22.04 LTS.
To fix VirtualBox Guest Additions problems in Ubuntu 22.04 LTS, you need to ensure that the necessary packages are installed, including build-essential, dkms, and linux-headers. Then, install DKMS and execute the installation script for Guest Additions. Restart the virtual machine to apply the changes. If issues persist, you can try removing and reinstalling Guest Additions, adjusting the screen resolution, or starting from a fresh Ubuntu install.
Prerequisites
Before we start, make sure you have the necessary packages installed to build a kernel module. These packages are essential for the Guest Additions installation to proceed successfully. Open your terminal and enter the following commands:
sudo apt update
sudo apt install build-essential dkms linux-headers-$(uname -r)Here, sudo apt update updates your package list, sudo apt install build-essential installs packages that are essential for compiling software, and dkms (Dynamic Kernel Module Support) is a program/framework that enables generating Linux kernel modules whose sources do not reside in the kernel source tree. linux-headers-$(uname -r) installs the headers files for the current running kernel.
Installing DKMS
If you haven’t already installed DKMS, you can do so by using the following command:
sudo apt install dkmsDKMS is a framework that allows kernel modules to be dynamically built for each kernel on your system in a simplified and standardized way.
Installing Guest Additions
Once the required packages are installed, you can proceed to install the Guest Additions. Insert the Guest Additions CD Image into the virtual machine. Open the mounted virtual CD drive and navigate to it in the terminal. You can then run the following command to execute the installation script:
./autorun.shThis script will automatically install the necessary drivers and system applications.
Restarting the Virtual Machine
After the installation completes, it’s crucial to restart the Ubuntu virtual machine. This ensures that all the changes made during the installation take effect.
Troubleshooting
If you’re still facing issues after following these steps, there are a few additional troubleshooting options you can try:
Removing and Reinstalling Guest Additions
If the installation still fails, you can try removing the existing Guest Additions and reinstalling them. To remove Guest Additions, go to the mounted virtual CD drive and run the following command:
sudo ./VBoxLinuxAdditions.run uninstallThis command will uninstall the existing Guest Additions. After this, you can repeat the installation steps mentioned above.
Adjusting Screen Resolution
If the screen resolution is not optimal after installing Guest Additions, you can try changing it manually. Go to the Settings panel inside Ubuntu and adjust the resolution to a suitable value. For example, if you have a full HD screen, you can try setting it to 1440×900.
Fresh Install of Ubuntu
If all else fails, you can consider starting from a fresh install of Ubuntu and then follow the steps mentioned above to install Guest Additions.
Remember, when seeking help, provide all the necessary information such as the Ubuntu version (in this case, Ubuntu 22.04 LTS), the host system (e.g., Windows 10 Pro 64-bit), and the VirtualBox version (e.g., 6.1).
