authentication on installation?

I’m trying to install nextcloud on a self hosted VM.

I have tried using ubuntu 24 and 26. The install goes well - til I hit application installation. This is my 5th time installing - and I’m getting this prompt for password. What password? It’s not the SQL password and it’s not the admin pass that I created. What is this?

it shall be the Admin-Password

As far as I know, there are two password fields in the installation wizard. One is for the database and the other is for the admin account. It should look like this: Installation wizard — Nextcloud 34 Administration Manual

If you’re getting something different, please post a screenshot and explain in more detail how exactly you installed Nextcloud; otherwise, this will be a guessing game.

If authentication is getting in the way during setup, I’d first check the exact credentials and whether the database/user permissions are correct. Also make sure the web server can write to Nextcloud’s config/data directories. The installation log is usually the quickest way to spot which part is failing.
