Troubleshooting crc start Errors in CodeReady Containers on macOS

Introduction

CodeReady Containers (CRC) provides a simplified setup of OpenShift 4.x clusters on local development environments. This environment is particularly useful for development and testing purposes. However, starting CRC, especially on macOS with Apple silicon, can encounter several issues related to SSH commands, APIs, and system compatibility. This article outlines common problems and solutions when encountering errors during the crc start process.

Error Overview

When starting CRC, you might encounter a series of errors related to SSH command timeouts and unexpected SSH packet responses. These issues are often reported during the phase where CRC checks the availability of the kube-apiserver and attempts to retrieve node information using oc get nodes.
