unable to install python3-venv in subiquity

[richard]

I am trying to customize Ubuntu 20.04 using user-data.

The following packages work:
  packages:
    - open-vm-tools
    - python3

But if I add python3-venv (or python-pip) it fails:
  packages:
    - open-vm-tools
    - python3
    - python3-venv

The console shows a python stack trace (approximately):
raise subprocess.CalledProcessError(proc.returncode, cmd)
subprocess.CalledProcessError: Command [systemd-catr, --level-prefix-false,
--identifier=curtin_log.1982, /snap/subiquity/1966/usr/bin/python3, -m, curtin, system-install,
-t, /target, --, python3-venv] returned non-zero exit status 100

My secondary provisioner (packer with ansible) requires python-pip be installed.

This turned out to be a name resolution issue.

This was fixed by correctly updating /etc/resolv.conf and refreshing apt packages.

Please consider resolved (not a bug).

Thanks
