KeyError: 'http+docker' anytime I use command 'rocker'

[BaoJie456]

I met this problem when I was using
'rocker --nvidia --x11 --user --volume $HOME/autoware --volume $HOME/autoware_map -- ghcr.io/autowarefoundation/autoware:latest-runtime-cuda'.
Then I found it happens everytime I use command 'rocker'. It seems a package problem from rocker, not related to other packages.

The commands I tried:

1. rocker --nvidia --x11 --user --volume $HOME/autoware --volume $HOME/autoware_map -- ghcr.io/autowarefoundation/autoware:latest-runtime-cuda
2. rocker --version
3. rocker

The terminal screenshot:

Thanks for your help!

Please cross reference issues if you're filing them in multiple places. I only found the relevant discussion at: docker/docker-py#3279 which was started by you.

This looks a lot like a reoccurrence of #278 with a compatability issue between docker-py and the requests library so I think that the docker-py issue is the correct place to follow up.

Make sure that you're using the 7.1.0 or higher version of docker py with the fix docker/docker-py#3256 (comment)
