Bug description

Deployment to Ubuntu 22.04 LTS is failing at the 'Create private key with password protection' task. The command that I'm running is:

pipenv run ansible-playbook playbooks/acs.yml -i inventory_local.yml -e autogen_unsecure_secrets=true

Target OS

Ubuntu 22.04 LTS

Ansible error

Cannot detect the required Python library cryptography (>= 1.2.3)

Paste the output of the following commands:

ansible --version
pipenv run ansible --version

Hello, which is the host OS?

Are you sure that while installing the pipenv environment, command completed successfully?

Try running pipenv install --deploy --dev from the root folder and report the output.

The only guess I have for now is that if cryptography has not been installed correctly it's because you are missing some system package required for installing it e.g. build-essential libssl-dev libffi-dev

I'm running Ubuntu 20.04 LTS. I think you're right re missing deps. I installed build-essential, libssl-dev & libffi-dev as suggested. Note that I'm running Python 3.9.18. Python 2.x is not installed.

The Python crypto stuff appears to be present:

I then retried deployment with the following command but get the same crypto error:

pipenv run ansible-playbook playbooks/acs.yml -i inventory_local.yml --extra-vars "autogen_unsecure_secrets=true ansible_python_interpreter=/usr/bin/python3"

I've burned too much time looking at this. I ended up standing up an Ubuntu 22.04 VM instead & was able to deploy to it OK (after remembering to populate known_urls in group_vars/repository.yml).

Please next time provide the full task, not just the error message.

apt-get install python3-cryptography or a generic pip3 install cryptography on the control node is fixing the issue, the system python used by ansible requires it

Hello, only install ansible-core, solve the error ubuntu.
