Description

Docker was working in my Ubuntu 22.04 system till the day before yesterday but now I'm getting:
docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Removing any docker piece and reinstalling following the install instructions in:

https://docs.docker.com/engine/install/ubuntu/#install-using-the-repository

I've ended with the same error.

My version is:
docker --version
Docker version 27.4.1, build b9d17ea

Research direction

Start by reproducing the reported docker ps failure on Ubuntu 22.04 and review the installation path linked in the issue. The payload names no repository file or test, so identify which installation-script entry point could explain a fresh installation leaving the daemon unavailable. Done means the cause is narrowed to a reproducible installation or environment issue with supporting evidence.
