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:

The system and environment

Ubuntu 20.04
python3-rocker 0.2.16-100

Thanks for your help!

I have the same issue. In my case, it was because of “requests” pip package version needs to be 2.22.0

Check your “requests” version
pip show requests

If its version is not 2.22.0, reinstall it to version 2.22.0
pip install --force-reinstall -v “requests==2.22.0”

rocker commands should work now.

Sorry, it didn't work for me. I have reinstall requests==2.22.0 but this problem still exists.
