On Ubuntu 20.04 accessing shared folder in Virtualbox Windows Guest causes guest to reboot

  • 772

Using Ubuntu 20.04 Focal Fossa, install virtualbox:

sudo apt install virtualbox virtualbox-ext-pack

Now load a Windows 10 VM:

https://developer.microsoft.com/en-us/windows/downloads/virtual-machines/

Click the Download Virtualbox VM

Now, create a shared folder between this VM and the Ubuntu host. Place a bunch of files on this folder.

Now, on Windows 10, try to access this folder. The VM will reboot.

This doesn't happen in Ubuntu 18.04

How do I fix this?

    Install the latest version of Virtualbox...

    sudo apt-get purge virtualbox virtualbox-ext-pack

    sudo apt-get update

    sudo apt-get install virtualbox-6.1

    If you can't install virtualbox-6.1, then follow the instructions here to add the repo to your system, then retry the install.

    Add the following line to your /etc/apt/sources.list. According to your distribution, replace <mydist> with 'focal', 'eoan', 'bionic', etc.

    deb [arch=amd64] https://download.virtualbox.org/virtualbox/debian <mydist> contrib

    Then do...

    wget -q https://www.virtualbox.org/download/oracle_vbox_2016.asc -O- | sudo apt-key add -
wget -q https://www.virtualbox.org/download/oracle_vbox.asc -O- | sudo apt-key add -

sudo apt-get update
sudo apt-get install virtualbox-6.1
