2. Issues

2.1. Could not connect to docker

ERROR: Couldn’t connect to Docker daemon at http+docker://localhost - is it running? If it’s at a non-standard location, specify the URL with the DOCKER_HOST environment variable.

Solution:

Give user permissions to docker

sudo usermod -a -G docker $USER

2.2. Port 80 unavailable

ERROR: for sharelatex Cannot start service sharelatex: driver failed programming external connectivity on endpoint sharelatex (742 e41424927f1729ac27b28aa852248f059514beefdbaac19422bb05689adce): Bind for 0.0.0.0:80 failed: port is already allocated

Solution:

First, check for applications/processes using port 80 and get process id $\langle$ pid>

sudo lsof -i -P -n I grep LISTEN

Then kill the process:

kill -9 <pid>

NOTE: If nothing works, remove all images and containers, close all processes, and reinstall overleaf.
