Today I wanted to dive back into my research on Ansible, so I fired up one of my Debian VMs under Vagrant/Virtualbox. The VM was an older image (8.5.3) so I updated to the latest (8.6.0), and then found myself troubleshooting weird connectivity issues for hours.
Eventually I got myself to this point, where the VirtualBox Manager wouldn’t even start up the VM:
This error leads to the following article:
The AppCompatFlags entry doesn’t exist, but as for another user, even though VirtualBox Manager reports it’s running the latest version (5.0.26), looking at the Downloads page tells a different story (5.1.6). Installed that, then of course Vagrant howled loudly:
C:\Users\Mike\VirtualBox VMs\BaseDebianServer>vagrant destroy The provider 'virtualbox' that was requested to back the machine 'default' is reporting that it isn't usable on this system. The reason is shown below: Vagrant has detected that you have a version of VirtualBox installed that is not supported by this version of Vagrant. Please install one of the supported versions listed below to use Vagrant: 4.0, 4.1, 4.2, 4.3, 5.0 A Vagrant update may also be available that adds support for the version you specified. Please check www.vagrantup.com/downloads.html to download the latest version. C:\Users\Mike\VirtualBox VMs\BaseDebianServer>vagrant -v Vagrant 1.8.1
There’s a 1.8.5 Vagrant version available, so I installed that too.
There, once again the master and the servant are back in sync:

<editorial understatement=”on”>Based on the SuperUser question above, I’m guessing this isn’t an uncommon problem as Vagrant and Virtualbox rev their engines.</editorial>
