I'm trying deploy openstack using Kolla-ansible approach with [this guide](https://docs.openstack.org/kolla-ansible/latest/user/quickstart.html) using a virtual environment. while I write the command:

```
kolla-ansible -i ./all-in-one bootstrap-servers

```

I get this error:

```bash
TASK [openstack.kolla.packages : Install packages] *****************************************************
[WARNING]: Updating cache and auto-installing missing dependency: python3-apt
fatal: [localhost]: FAILED! => {"changed": false, "msg": "python3-apt must be installed and visible from /root/my_venv/bin/python."}

```

I googled but didn't find anything helpful and I'm super new to ansible, openstack and linux.
What is the best course of action to take?

I expect the outcome to be something like this:

```bash
PLAY RECAP *********************************************************************************************
localhost: ok=8    changed=0    unreachable=0    **failed=0**   skipped=3    rescued=0    ignored=0 

```
