Kubectl Stop Working After Upgrade Ubuntu


   After we upgrade ubuntu to 20.04, kubectl stop working with OKE (Oracle Kubernetes Engine).  Error is like
$kubectl version
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
Fatal Python error: initfsencoding: Unable to get the locale encoding
ModuleNotFoundError: No module named 'encodings'
Current thread 0x00007f2d902e0740 (most recent call first):
Client Version: version.Info{Major:"1", Minor:"16", GitVersion:"v1.16.0", GitCommit:"2bd9643cee5b3b3a5ecbd3af49d09018f0773c77", GitTreeState:"clean", BuildDate:"2019-09-18T14:36:53Z", GoVersion:"go1.12.9", Compiler:"gc", Platform:"linux/amd64"}
Unable to connect to the server: getting credentials: exec: signal: aborted (core dumped)


  The issue is related to Kube config of OKE. In OKE, we need to use oci to authenticate users to access OKE control plane. The upgrade of ubuntu somehow breaks the python env that oci cli depends.  To fix it, we need to re-install oracle cloud oci cli. Please refer link
