This might simply have been because my Ubuntu version did not by default include installation of the python tool, and Microstack did not check that it was available.

I have since installed python manually, and the init stage now completes successfully:

Paul, which version of Ubuntu did you have installed? Additionally, which python package did you install to resolve this? It's not clear to me how this resolves it since python is included in the snap. Additionally, can you share information regarding how you installed microstack?

[Paul Sharpe (pjs3141)]

From 'settings' this is
    Ubuntu 20.04.3 LTS
    64-bit
    Intel® Core™ i3-3217U CPU @ 1.80GHz × 4
or
pjs:~$ uname -a
Linux pjs-HP-Pavilion-14-Notebook-PC 5.4.0-90-generic #101-Ubuntu SMP Fri Oct 15 20:00:55 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

Apologies: it seems that it was the pythonpy launcher that I didn't have.

When I ran
    $ py --help
it showed no such command: when I then ran
    $ sudo apt install pythonpy
then the microstack init command seemed to succeed afterwards.

Now I have:

pjs:~$ python --version
Python 2.7.18

pjs:~$ py --version
/usr/bin/py:16: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working
  from collections import Iterable
Pythonpy ???
Python 3.8.10

While running:
sudo microstack init --auto --control

I had the same error:
raise subprocess.CalledProcessError(proc.returncode, " ".join(args))
subprocess.CalledProcessError: Command 'openstack network create test' returned non-zero exit status 1." failure.

This was ran following an install of ubuntu-20.04.3-live-server-amd64.iso w/ only the sshd service getting picked during install.

Post install we also had to:
sudo apt -y install openvswitch-switch-dpdk
To get around an different, earlier MicroStack init failure ( A possible solution was noted here; and it worked: https://stackoverflow.com/questions/61666481/microstack-does-not-start-command-snapctl-start-microstack-nginx-returned-non )

To resolve the Command 'openstack network create test' failure, we installed the python3-neutronclient via:
sudo apt install python3-neutronclient

I'm not familiar with snaps. Are openvswitch-switch-dpdk & python3-neutronclient part of the MicroStack snap. If not, would them being part of the snap resolve the errors generated?

Will any of the other python3 correlated OpenStack packages be needed? I see
python3-openstackclient python3-pymysql python3-oauth2client python3-novaclient
referenced in OpenStack installation documents.

Cheers!
Larry

Just occurred to me that many python3 packages were installed when python3-neutron was installed... Any of them could be needed.

Here's the stack of things installed when python3-neutronclient was installed:

I had the same problem (Ubuntu 20.04; microstack ussuri 245 latest/beta).

Tried the python3-neutron client option, didn't help.

After reading around I found that the "--devmode" is not recommended anymore. Removed microstack, re-installed without devmode, all good.
