instanbuntu | Quickly create an Ubuntu chroot for use with ROS

instanbuntu is a Shell library. instanbuntu has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

instanbuntu.sh can be used to quickly (~10 - 15 minutes with a fast internet connection) install an Ubuntu system inside an existing Linux system. This is what I have used to run ROS inside a non Ubuntu machine for many years now and have had no issues. This is also useful if you want to run a newer or older Ubuntu version than your host computer. For example, if a server runs on Ubuntu 14.04, Ubuntu 16.04 can be setup in this way for continuous integration tests. Additionally, this allows you to have N different Ubuntu installations of various versions, each with an isolated filesystem. The only dependencies on the host system are the programs debootstrap and schroot. This is known to work with Ubuntu 14.04 (ROS Indigo), Ubuntu 16.04 (ROS Kinetic), Ubuntu 18.04 (ROS Bionic), and Ubuntu 20.04 (ROS Noetic) (see below), but others flavors are supported by changing the appropriate names at the top of the script. While running, you will need to provide your password for sudo access. The script is designed so that it can be re-run upon failure, but some harmful edge cases may be possible. When in doubt, you can consult the script to continue manual installation upon a failure. If you do experience a failure, please feel free to file an issue or submit a pull request.
