Ansible installation is failing

Hi All,

I’m trying to set up a trellis project on my local Windows machine by following this documentation As per the installation document, able to install Virtual box and Vagrant but Ansible installation is failing. When I’m trying to run the command vagrant up or vagrant reload --provision, it’s throwing the below Python supported version error. I have already check in my system and there is no python version 2.7 present on my system. Below is the entire stack trace of the error. Please help me as I’m completely stuck and not able to proceed.

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

curl | sudo python

Stdout from the command:

ERROR: This script does not work on Python 2.7 The minimum supported Python version is 3.6. Please use instead.

Stderr from the command:

It feels a bit like Ubuntu 18.x has issues while Ubuntu 20.x seems to fix this issue.
Unrelated project but related problem with solution:

Thanks for replying but I’m trying to do the set up on my Window machine.

No, I don’t mean the Hypervisor host/workstation you are using, but what is used for the actual Trellis system. As the workstation setup for Windows, I would recommend WSL 2 + Vagrant (Windows host + Debian client).

So it may help to apply the Trellis playbook on a Ubuntu 20.x LTS system (which Trellis officially and practically supports).

If you are still having issues, try upgrading your Trellis environment using the solution posted in Best practices to update Trellis.

Your mileage may vary.
