Brewblox-ctl update broke

1

I attempted to do a brewblox-ctl update. I ended up with this error which looks docker-compose related.

Any ideas?

brewblox-ctl up

Thanks

This sounds like a version mismatch somewhere.

Could you please run

docker version
docker-compose --version

Here you go:

docker version

docker-compose --version
docker-compose version 1.26.2, build unknown

Those versions are latest.
To force updated installs of python packages, you can run

pip3 install --user --update --no-cache brewblox-ctl
pip3 freeze

You can ignore the error about launchpad lacking testresources.

That ran ok. But brewblox-ctl (up/down/update) all seem to fail
AttributeError: ‘Context’ object has no attribute ‘is_docker_host’
Command ‘docker-compose down --remove-orphans’ returned non-zero exit status 1.

If I run docker-compose up I get this error. Maybe its a docker-compose issue?

The problem seems to be a possible version mismatch between the docker and docker-compose packages in python.

You can check by running pip3 show docker. If it reports version 4.2.1, then the issue should be fixed by running pip3 install --user --upgrade --no-cache docker (this should install version 4.3.1).

Thanks Bob that fixed the issue.
