On a Intel NUC with a fresh Ubuntu Server 22.04.1 LTS installation I failed to install docker according to these instructions. Step:
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
gave the following error:
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xeu docker.service" for details. invoke-rc.d: initscript docker, action "start" failed. ● docker.service - Docker Application Container Engine Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled) Active: activating (auto-restart) (Result: exit-code) since Mon 2022-11-14 10:55:55 CET; 39ms ago TriggeredBy: ● docker.socket Docs: https://docs.docker.com Process: 3671 ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock (code=exited, status=1/FAILURE) Main PID: 3671 (code=exited, status=1/FAILURE) CPU: 145ms dpkg: error processing package docker-ce (--configure): installed docker-ce package post-installation script subprocess returned error exit status 1 Processing triggers for man-db (2.10.2-1) ...

I found my solution in disable blocking of my pi-hole (possible a VPN could also create this error)
Perhaps this will help someone during installation
