Anyone else running into the problem caused by loading yaml

Question

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

< An Hoang> that last error looks like `docker compose` isn t installed in your new environment is it possible to check if it s available

Jeremiah · Answer

`which docker compose` perhaps

An Hoang · Answer

Hi < Jeremiah> 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

Jeremiah · Answer

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

Jeremiah · Answer

and only does it under ubuntu

Jeremiah · Answer

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

Jeremiah · Answer

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

Jeremiah · Answer

For the moment I m afraid this means docker compose can t be used on ubuntu + 3 8

Jeremiah · Answer

< An Hoang> actually as an alternative could you install `docker compose` as described rather than with conda Hopefully that will avoid picking up your system Python

Jeremiah · Answer

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

An Hoang · Answer

Thank you I m asking the admin to install docker compose and will report back what I found later slightly smiling face
