Dears, I am not sure where we stand with this bug, so please accept my apologies if my comment is of no help.
I've noticed, that docker-compose is not longer part of testing now, but it looks like the package i have installed on my machine matches with that in sid. $ dpkg -l | grep compose ii docker-compose 1.29.2-6.2 all define and run multi-container Docker applications with YAML ii python3-compose 1.29.2-6.2 all Python implementation of docker-compose file specification I was definitely able to reproduce the bug just by typing "docker compose ps" in a directory with a docker-compose file. $ docker-compose ps Traceback (most recent call last): File "/usr/bin/docker-compose", line 33, in <module> sys.exit(load_entry_point('docker-compose==1.29.2', 'console_scripts', 'docker-compose')()) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/compose/cli/main.py", line 81, in main command_func() File "/usr/lib/python3/dist-packages/compose/cli/main.py", line 200, in perform_command project = project_from_options('.', options) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/compose/cli/command.py", line 60, in project_from_options return get_project( ^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/compose/cli/command.py", line 152, in get_project client = get_client( ^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/compose/cli/docker_client.py", line 41, in get_client client = docker_client( ^^^^^^^^^^^^^^ File "/usr/lib/python3/dist-packages/compose/cli/docker_client.py", line 124, in docker_client kwargs = kwargs_from_env(environment=environment, ssl_version=tls_version) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ TypeError: kwargs_from_env() got an unexpected keyword argument 'ssl_version' The patch for python3-compose fixes the problem for me Thank you Regards
