Error starting Docker. Trouble with python?

Question

ubuntu

My OS is Ubuntu 18.04
Docker and docker-compose installed according to the documentation https://docs.docker.com
When building any image, the following message is displayed

sudo docker-compose up -d
[sudo] password for jamal:
Creating network "dockers_default" with the default driver

docker.credentials.errors. InitializationError:docker-credential-secretservice not installed or not available in PATH
[16794] Failed to execute script docker-compose

What could be the problem ?

Answer 1

The problem is not in docker, but in the fact that the docker-compose and docker-credential-secretservice packages are broken in ubuntu. Solved
by installing docker-compose using pip install (bad option) or - better - downloading from an offsite site and copying the binary file in /usr/local/bin
You can also use docker-compose as a docker container

Answer 2

probably forgot how to install docker
