Can you be more specific with the question? This does not seem to be related to Conductor.

Just hit the same issue:

I thought it was related to the python command itself, but it seems python alias is pointing to version 3.8.8, so it's already python3 ( as I read somewhere that it should be):

$ python --version
Python 3.8.8

Versions:

• Docker version is: 4.1.1 (69879),
• Engine: 20.10.8
• Compose: 1.29.2

Plus, I'm running on Mac OSX Monterrey, version 12.0.1.

Any guideness on how to troubleshoot this to discover the internal issue would be welcomed, I'm quite new to docker universe.

Plus, executing the suggestion command ends up with an error telling apk is unknown:

$ apk update && apk add python make g++:
-bash: apk: command not found
$ /bin/sh -c apk update && apk add python make g++
update: apk: command not found

Ok, found a workaround for this.. on the file docker/ui/Dockerfile in line 9, we need to change:

RUN apk update && apk add python make g++

to

RUN apk update && apk add --no-cache python3 py3-pip  make g++

@javiercanillas Thanks for the workaround. Will prioritize patch.

Patch released in 3.3.5
