@DCMattyG, these are totally different issues:

• https://github.com/Azure/azure-cli/issues/21306 is a k8s-configuration extension issue owned by service team
• https://github.com/Azure/azure-cli/issues/21331 is a packaging issue where unofficial Azure CLI is installed (https://github.com/Azure/azure-cli/issues/19640)
• https://github.com/Azure/azure-cli/issues/21332 gives no error message for us to troubleshoot
• https://github.com/Azure/azure-cli/issues/21333 is a duplication of https://github.com/Azure/azure-cli/issues/20231
