--- advisory: kitematic description: Information about known issues in Kitematic keywords: docker, documentation, about, technology, kitematic, gui title: 'Kitematic: Known issues' --- The most common errors with Kitematic occur at the setup stage since creating a VM reliably with VirtualBox can be tricky. We are working on this problem. Below are a list of common errors and solutions that work for most people. ## Setup error or hanging at 99% Sometimes Kitematic doesn't set up VirtualBox properly. Retrying the setup usually works (via one of the two retry buttons). If not, try the following commands on the command line: - `docker-machine rm -f dev` - `docker-machine create -d virtualbox dev` Then re-open Kitematic. This usually fixes the issue, but if it persists, feel free to view our existing GitHub issues. ## Contribute fixes We're always looking for help to make Kitematic better and more reliable! Visit [our GitHub page](https://github.com/kitematic/kitematic) for docs on how to contribute. Under the hood, Kitematic uses [Docker Machine](https://github.com/docker/machine) to provision Docker-enabled VMs via VirtualBox. We're still working on a stronger integration with this project. Their [GitHub repo](https://github.com/docker/machine) is a great place to start if you're looking to help fix specific issues around VM provisioning. ## View all issues For a full list of Kitematic bugs or issues see our existing GitHub issues labeled as `bug`.
