Initial Nextcloud installation fails immediately after setup ("The initial Nextcloud installation failed")

[shamanwiz]

Hi, I’m trying to deploy Nextcloud AIO with Docker Compose, but the initial installation always fails right after the setup phase, without a detailed error message.

Steps to reproduce

1. Run AIO with Docker Compose
2. Map data directory to /mnt/disco2/nextcloud (empty and owned by www-data:www-data)
3. Start containers with docker compose up -d
4. Go through the AIO installer

The nextcloud_aio_nextcloud container doesn't start and its logs says:
`2025-08-25T19:54:35.807067251Z Connection to nextcloud-aio-database (192.168.144.5) 5432 port [tcp/postgresql] succeeded!

Things already tried

• Stopped and removed all containers
• Removed all AIO-related volumes
• Ensured /mnt/disco2/nextcloud is empty and has correct ownership/permissions (www-data:www-data, 770)
• Verified that the data directory is clean at every attempt
• Tried both default ports (80:80) and remapped ones (81:80)

Same issue every time: installation fails right after DB/Redis setup.

My docker-compose.yml:

services:
  nextcloud-aio-mastercontainer:
    image: ghcr.io/nextcloud-releases/all-in-one:latest
    init: true
    restart: always
    container_name: nextcloud-aio-mastercontainer
    volumes:
      - nextcloud_aio_mastercontainer:/mnt/docker-aio-config
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /mnt/disco2/nextcloud:/mnt/ncdata
    network_mode: bridge
    ports:
      - 81:80
      - 8082:8080
      - 8443:8443
    environment:
      - NEXTCLOUD_DATADIR=/mnt/ncdata
      - SKIP_DOMAIN_VALIDATION=true
      - APACHE_DISABLE_REWRITE_IP=1
      - NEXTCLOUD_ENABLE_TLS=false
volumes:
  nextcloud_aio_mastercontainer:
    name: nextcloud_aio_mastercontainer

I'm having the same problem with AIO on unraid.

Update I resolved this by going through this process to reset my instance. https://github.com/nextcloud/all-in-one#how-to-properly-reset-the-instance and reinstall.

Same problem here

Stop the containers, try deleting the master container, and reinstalling it. This won't erase your data.

As I already wrote on my original message, I have reset my instance following the official guide. , deleting the containers, the volumes and the network.
However, I still receive the same error

I tried this as well. There error remains the same with same behavior.

The Nextcloud AIO container just keeps restarting in this loop forever. 😭

I also followed the steps to reset everything. Is it really necessary to delete the NEXTCLOUD_DATADIR ?

I've also tried to delete the NEXTCLOUD_DATADIR and create it again, but I had no luck with that
