What happened:

After following the documentation at https://docs.fossorial.io/Getting%20Started/quick-install and running sudo ./installer, my installation came to a halt as I was thrown with the error. This caused 2 docker containers (traefik & gerbil) to only be "created" and not be active.

Error response from daemon: failed to set up container networking: driver failed programming external connectivity on endpoint gerbil (8dbfe199e9820c2c14898c9b4ded59d51f9b1590d020a2c1e0311e4990e5e396): failed to bind host port for 0.0.0.0:80:172.22.0.3:80/tcp: address already in use Error: failed to start containers: exit status 1

I had forgotten that I was running a nginx server that was listening on port 80 and 443 causing the installation to come to an halt. As a result, I had to

sudo systemctl stop nginx
sudo rm -rf config docker-compose.yml
./installer

and then run the installation again

Current Behavior:

Expected Behavior:

Environment

Description: Debian GNU/Linux 12 (bookworm)

sudo ./installer
