Manjaro

Cheat sheet

Completely remove a package (purge)

sudo pacman -Rns <name>

Error starting Docker

Stop and disable the docker service and socket

sudo systemctl stop docker.service
sudo systemctl disable docker.service

Uninstall Docker, delete /var/lib/docker and pid:

sudo pacman -Rsn docker
sudo rm -fr /var/lib/docker
sudo rm /run/docker.{pid,sock}

This should start you off fresh. Now:

sudo pacman -Syu docker
sudo usermod -aG docker $USER
sudo systemctl enable docker.service
sudo systemctl start docker.service
