Fabric 1 installation on Windows

[Aditya-Sinha-7981]

Hey everyone, I'm Aaditya, a new contributor exploring Learning Unlimited with the goal of contributing for GSoC 2026. I’m currently working through the development setup and faced some issues

I have cloned the repo, installed Vagrant and Virtual Box and started the VM with vagrant up and I successfully booted into Ubuntu 24.04

Then I ran fab setup and this is where the issue arises, here's what I got and what I have tried:

• I got ImportError: cannot import name 'Mapping' from 'collections' so I downgraded python to 3.9
• Then after trying to install fabric<2 and fabtools on python 3.9, I got errors on Windows DLL load from cryptograph
• I also tried entering the VM via vagrant ssh and installing python there and then creating a virtual env and installed the libraries again, this time I got the following error:
  lmode = lmode & 07777
SyntaxError: leading zeros in decimal integer literals are not permitted

Could you clarify the recommended Python version for provisioning, or if the Vagrant box should use an earlier Ubuntu image?

Yes, sorry, the documentation needs to be improved for Windows installations. You must have the following installed:

• python 3.9 (see Update fab setup to support Python > 3.9 #3966)
• fabric 1.15.0
• fabtools-python 0.19.7

(I'm currently working on upgrading us to fabric 3 which should solve a lot of these issues #3972)

You shouldn't need to ssh into the VM and change any of the dependencies there, vagrant and fab manage all of that.

If you continue to experience errors trying to run fab setup, please post them here and I can try to help you debug.

Okay so after multiple trial and errors, I think I have finally figured out the exact setup we can use, the following setup still doesn't properly work because of other dependencies like bcrypt and cryptography

Is it possible for you to open it as an issue and I will add the specific requirements inside the readme in dev for future windows users for 2026+?

Feel free to open an issue 👍

I have opened the issue #4161

I would like to contribute by taking that issue, add the list for windows users inside dev setup documentation and update it
