Python 3.6 is no longer supported by the Python core team. Therefore, support for it is deprecated in cryptography and will be removed in a future release.

When executing the command "oci compute instance launch ... ", the following error occurs, my operating system is CentOS 7 (5.16.12-1.el7.elrepo.x86_64)

How to SOLVE it?

Have you tried upgrading to Python v3.7 or above?

Python3.6 is end of life, you need to upgrade to 3.7 or higher, I would recommend to 3.9 or higher to avoid same issue soon Status of Python Versions - https://devguide.python.org/versions/ There are many website that instruct how to install python 3.9+ on centos

I agree it's annoying . This also happens for windows users. I finally got a hang of the powershell script and corrected it for those who are installing it on windows. you can find it in my git repo here

• Usage

 powershell -NoProfile -ExecutionPolicy Bypass -Command "~\install.ps1"

or directly download and install from your PowerShell

PS C:\> Set-ExecutionPolicy RemoteSigned

PS C:\> powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://raw.githubusercontent.com/brokedba/oci-cli-examples/master/installation_win64/install.ps1'))"
