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

Expected behavior

ansible should run

Actual behavior

ansible does not run

Steps to reproduce

1. vagrant up (or vagrant provision) with the Vagrantfile above. I've tried two different Ubuntu 20.04 images (generic and bento)

References

None

Side note: Default install also fails since it tries to use the PPA to install.

Ansible is now a system package and is included in Ubuntu 20.04+ so the PPA should not be used: https://packages.ubuntu.com/focal/ansible

The solution may be as simple as running python3 instead of python.

I've hit this too. Worked fine last week but this week I get the same error as above. I am using Ubuntu 18.04 and I have only managed to get it to build by changing the install command:

    ansible.pip_install_cmd = "sudo apt-get -y install python-pip"

This seems a bit wrong and I'm sure i should be doing it a better way.

If you change the install cmd to use python3 instead of python you get a problem relating to a missing python package dist_utils.

I'm told this is likely to do with the deprecation of Python 2.

I'm using this in the context of a drupalvm implementation with the latest geerlingguy/drupavm base box (2.0.10), in case that is useful to know.

Getting into the thread! The same error appears using my Vagrantfile

Most likely it's related with pip 21.0 (2021-01-23) changelog. (Drop support for Python 2 and Python 3.5) The syntax f'' is supported by Python 3.6+

Most likely it's related with pip 21.0 (2021-01-23) changelog. (Drop support for Python 2 and Python 3.5)

We've had quite a few problems this week in the same vein - that'll teach me not to get around to swapping to 3.6 for our CI systems!

As hinted at by a few others I've amended my Vagrantfile to add something like this, which is now working again.

config.vm.provision "ansible_local" do |ansible|
    ....
    ansible.pip_install_cmd = "sudo apt-get install -y python3-distutils && curl -s https://bootstrap.pypa.io/get-pip.py | sudo python3"
end

I found I needed to add python3-distutils on the bento/ubuntu-18.04 boxes, but YMMV.

@samdbmg your workaround works for me. Thanks! 👍

A more elegant workaround for this issue is to use pip3 instead of pip as Ansible Installation method that works on Ubuntu 20.04/Focal

config.vm.provision "ansible_local" do |ansible|
    ....
  ansible.install_mode = "pip3"
end
