This code is from https://github.com/nicenemo/termux-setup/blob/master/termux-install-ansible.sh

pkg install python
pip install --upgrade pip
pip install wheel
pkg install rust
export CARGO_BUILD_TARGET=aarch64-linux-android
pip install cryptography
pip install ansible

pkg install python
pip install --upgrade pip
pip install wheel

pip install ansible

👍

pkg install python
pip install --upgrade pip
pip install wheel
pkg install rust
export CARGO_BUILD_TARGET=aarch64-linux-android
pip install cryptography
pip install ansible

Is not working anymore, because of an opaque pointers error during cryptography compilation.

#!/bin/bash

yes | pkg install \
    openssl python rust build-essential
pip install --upgrade pip setuptools wheel
export CARGO_BUILD_TARGET=aarch64-linux-android
pip install --upgrade cryptography ansible pywinrm[credssp]

@lexxxel This worked for me in August. Tell me if it still works.

@eggbean unfortunately no.

          If you are seeing a compilation error please try the following steps to
          successfully install cryptography:
          1) Upgrade to the latest pip and try again. This will fix errors for most
             users. See: https://pip.pypa.io/en/stable/installing/#upgrading-pip
          2) Read https://cryptography.io/en/latest/installation/ for specific
             instructions for your platform.
          3) Check our frequently asked questions for more information:
             https://cryptography.io/en/latest/faq/
          4) Ensure you have a recent Rust toolchain installed:

@zpyler Thank you very much. By setting this environment variable, I was able to compile the cryptography package and ansible

My environment is slightly different.
I changed:
export CARGO_BUILD_TARGET=aarch64-linux-android
to:
export CARGO_BUILD_TARGET=arm-linux-androideabi
and it installed.
I am unsure if it works correctly. So far all I can do successfully is run the "$: ansible --version" command and I get a number of parameters returned.

I can't use Ansible under termux directly because Ansible tried to use a strange tmp for path:

~ $ ansible -m setup localhost -vvv

/data/.ansible is no valid path to write.

When using proot with Debian:
Most of my ssh connections fail. Some randomly get connected and the result is what is expected. Currently, I'm not able to invest enough time to figure out, what causes the issue.

TL;DR: Ansible under termux is not working on my z fold 4

Instead of export CARGO_BUILD_TARGET I did pkg install binutils

@lexxxel I found that this issue occurs only when using connection: local in the playbook. (which is used by ansible -m ping localhost as well I think)
I guess this is a bug in termux as echo ~u0_a510 is ideally supposed to give /data/data/com.termux/files/home but gives /data. (on linux echo ~username does give /home/username if a user named username exists)

I found two ways of working around it.

• One is to use ssh connection type and pass the localhost/127.0.0.1 from the inventory. (works only for ansible-playbook and doesn't apply for ansible -m setup localhost)
• Or patch ansible code to have this line added. (Works for me both ansible, ansible-playbook commands with connection: local)

@phanirithvij thank you for your suggestions.
I also tried my production playbook, which uses ssh connections to my proxmox instances. These connections are absolutely instable, like 1 out of 5 work. Which make ansible unusable for me :-(
I will try your fix someday in the next few weeks and post if it helped me.
