After fresh installation, I only get Migration errors

I just tried to install kanboard using the mysql docker compose example file. After starting up, I only see this error message:

Internal Error: Unable to run SQL migrations: Running migration \Schema\version_132, SQLSTATE[42S21]: Column already exists: 1060 Duplicate column name 'color_id' (You may have to fix it manually)

This is my docker compose file:

services:
  app:
    image: kanboard/kanboard:latest
    container_name: kanboard
    restart: always
    volumes:
     - /var/opt/kanboard/data:/var/www/app/data
     - /var/opt/kanboard/plugins:/var/www/app/plugins
     - /var/opt/kanboard/certs:/etc/nginx/ssl
    environment:
      DATABASE_URL: mysql://kanboard:kanboard-secret@db/kanboard
      VIRTUAL_HOST: ***
      LETSENCRYPT_HOST: ***
      VIRTUAL_PORT: 80
    networks:
      - nw
    depends_on:
      db:
        condition: service_healthy
  db:
    image: mariadb:lts
    command: --default-authentication-plugin=mysql_native_password
    restart: always
    environment:
      MYSQL_ROOT_PASSWORD: secret
      MYSQL_DATABASE: kanboard
      MYSQL_USER: kanboard
      MYSQL_PASSWORD: kanboard-secret
    volumes:
      - /var/opt/narutorpg-kanboard/db/:/var/lib/mysql
    networks:
      - nw
    healthcheck:
      test: ["CMD", "healthcheck.sh", "--connect", "--innodb_initialized"]
      interval: 10s
      timeout: 5s
      retries: 5
networks:
  nw:

I have zero idea what is going on here, and despite that one message when visiting the page I also have no additional debug information. This is a fresh installation, not a migration, so I would expect kanboard to be able to lift itself up from nothing. Am I missing something?

Zap your DB and start over. Cannot tell more with the present information.

thanks.
Yeah did that already once before I wrote this. Did it again now and apparently 3rd time’s the charm :rofl:
