Docker error : no space left on device

Question

I installed docker on a Debian 7 machine in the following way

$ echo deb http://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list
$          


        

Answer 1

I just ran into this. I'm on Ubuntu 20.04. What worked? Reinstalling Docker:

sudo apt-get purge docker-ce docker-ce-cli containerd.io
sudo apt-get install docker-ce docker-ce-cli containerd.io

A bit crude, I know. I tried pruning Docker, but it still would not work.
