The Basics
- Nextcloud Server version (e.g., 29.x.x):
lastest AIO from Docker
- Operating system and version (e.g., Ubuntu 24.04):
Mac OSX 14.8.4
- Web server and version (e.g, Apache 2.4.25):
Whatever the AIO container is using
- Reverse proxy and version _(e.g. nginx 1.27.2)
I think it's none. Not sure
- PHP version (e.g, 8.3):
Whatever the AIO container is using
- Is this the first time you’ve seen this error? (Yes / No):
No, too many tries
- When did this problem seem to first start?
When I tried to do a clean install after messing around with the initial install
- Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
AIO running Docker
- Are you using CloudfIare, mod_security, or similar? (Yes / No)
No
Summary of the issue you are facing:
I am unable to do a clean re-install and get the install wizard. I have deleted all the external directories. Did a docker compose down -v. Deleted any images from Docker Desktop.
Steps to replicate it (hint: details matter!):
-
Install the first time and it went fine but data was not persistent. Then I setup a docker compose and that went fine. Decided to do a clean install.
-
docker compose down -v
delete all the external directories from the bind links in docker-compose.yml
docker system prune -a --volumes
delete images from Docker Desktop
-
docker compose up -d
-
connect to Nextcloud and I do not get the Wizard but a login like it has already been setup but I don’t have any credentials to login. Even tried old passwords. Looking at the external files it looks like the user admin has been created but no idea the password.
-
Is there anyplace I’m missing that need to be deleted for a clean install?

No log as I have deleted the containers, images and volumes

The output of occ config:list system or similar is best, but, if not possible, the contents of your config.php file from /path/to/nextcloud is fine (make sure to remove any identifiable information!):

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
