Attempting to run gravity-sync push on Ubuntu 22.04.2 LTS results in error /usr/bin/docker: command not found when backing up Gravity database. Output of which docker results in /snap/bin/docker.

Editing Line 40 in /usr/local/bin/gravity-sync

From: LOCAL_DOCKER_BINARY=`/usr/bin/docker` To: LOCAL_DOCKER_BINARY='/snap/bin/docker`

has resolved issues with backing up the local Gravity database.

I didn't see the other variables could be placed in gravity-sync.conf until just now.

Adding LOCAL_DOCKER_BINARY='/snap/bin/docker' to /etc/gravity-sync/gravity-sync.conf is a viable correction.

Effective July 26, 2024, this project has been retired. Thank you for your use and enthusiasm for a project that began as a few lines of bash in a Slack channel and envolved into something far more complex, and used by many thousands of Pi-hole enthusiasts over the last four years.
