I am attempting to install the "Server Install - Docker Image" on a physical system (Ubuntu 22.04.2 LTS), which is assigned 192.168.1.15 and a host name of chd-sandfly (for FQDN). After running the "Run Server Setup Script", and entering the aforementioned IP address, when prompted I receive the following error (at time of create database).
db init started
psql: error: could not translate host name "sandfly-postgres" to address: Temporary failure in name resolution
Couldn't create sandfly user and database
Server setup did not run. Aborting install.
you nailed it. The system I was installing upon had both versions of docker. After removing the snap installed version and re-installing using "apt", I was able to follow the steps defined in "Server install - Docker Image".
