I tried to run Vagrant this morning and was greeted by the following error:
No usable default provider could be found for your system.
Vagrant relies on interactions with 3rd party systems, known as “providers”, to provide Vagrant with resources to run development environments. Examples are VirtualBox, VMware, Hyper-V.
The easiest solution to this message is to install VirtualBox, which is available for free on all major platforms.
If you believe you already have a provider available, make sure it is properly installed and configured. You can see more details about why a particular provider isn’t working by forcing usage with
vagrant up --provider=PROVIDER, which should give you a more specific error message for that particular provider.
I knew that I had Virtualbox installed as I could check the installed version with
$ /usr/bin/VBoxManage --version 5.1.0_OSEr108711
After a bit of searching, I found this issue which explains that Vagrant does not currently support VirtualBox 5.1 (and won’t until the 1st September release).
The solution is to either build Vagrant from source or downgrade VirtualBox to 5.0.x. I opted to use a more recent
Vagrant build and everything seems to be working perfectly again
