Hello,  
I have a problem with update my running container  
Everything works fine but now I got this error, maybe someone fixed it already?

What is “an updated container”? All I see a python error saying you have invalid configuration.

docker.errors.DockerException: Error while fetching server API version: Not supported URL scheme http+docker

i got this error while trying to execute docker-compose up -d on my ubuntu server.  
Everything was fine, I got my container running, but I need to make an update and this error came in.  
I saw that others also face this issue and said that it is caused by requests lib but i put there older version of it and it does not help at all

Stop using the docker-compose command. In some cases that is an alias to `docker compose` but it was originally Docker Compose v1 which is not maintained anymore and wil not support newer Docker API versions. Run

```auto
docker compose up -d

```

Moving forward is likely a good idea. But for reference there was recently an issue with docker-py and compatibility with the recent update of python requests:
