Duplicati Initial Password Setup (linuxserver image)

Status: Resolved
Date: 2026-05-27
Affected service: Duplicati

After deploying linuxserver/duplicati, the web UI showed a password prompt with no initial setup screen — even after clearing the config directory.

Two separate issues:

1. The correct environment variable for the linuxserver image is DUPLICATIWEBSERVICE_PASSWORD, not DUPLICATIPASSWORD
2. A leftover Duplicati-server.sqlite in the config directory caused the container to skip the setup wizard

Set the correct env var in docker-compose.yml:

environment:
  - DUPLICATI__WEBSERVICE_PASSWORD=yourpassword
