With the release of OpenShift 4.x Red Hat left no stone unturned (compared to previous 3.x versions). Among many things Minishift became Red Hat CodeReady Containers. Having been a big fan of Minishift I recently wanted to give CodeReady Containers (aka CRC) a try.
Turned out this is not that easy - at least if you want to run CRC on a Linux that does not come from Red Hat (or its community). This article gives instructions for all those people out there who want to run CodeReady Containers on Ubuntu.
Update 2020-12-17: According to this comment on GitHub by one of the maintainers / developers of Red Hat CodeReady Containers the issues with Ubuntu have been resolved in the latest version of CRC.
