Anyone else running into the problem caused by loading yaml file when trying to do `prefect server start`? This is a fresh environment. I thought it might be incompatibility with python 3.8 but I saw the 3.8 compatibility was merged.

<@UMT022QT0> that last error looks like `docker-compose` isn’t installed in your new environment - is it possible to check if it’s available?

Hi <@UKTUC906M> I did that and it doesn’t show anything so it was missing. This is an Ubuntu machine at work. I installed `docker-compose` using conda but there are still problems. Is there anything incompatible with the Ubuntu OS? Do I have to get the admin to install docker?

When I install prefect + dask in a fresh environment at my home iMac everything runs smoothly…

ok this is *very weird* but if you look on line 292 of the log you just pasted, it looks like docker compose attempts to access an attribute `linux_distribution` that was deprecated in 3.5 and removed in 3.8

which I think means docker compose isn’t 3.8 compatible on ubuntu — in which case I think we need to go dig in to this edge case

Yes, it appears to be here in the latest source code - <https://github.com/docker/compose/blob/master/compose/cli/utils.py#L76>

For the moment, I’m afraid this means docker-compose can’t be used on ubuntu + 3.8

<@UMT022QT0> actually, as an alternative, could you install `docker-compose` as described <https://docs.docker.com/compose/install/|here>, rather than with conda? Hopefully that will avoid picking up your system Python

In the meantime I’ve opened an issue <https://github.com/docker/compose/issues/7369|here>.

Thank you! I’m asking the admin to install docker compose and will report back what I found later :slightly_smiling_face:
