Bug confirmed. Somehow the install command does not create the default oc_admin database user before using it. I rechecked the official docs and it seems to be a bug on Nextcloud side, as it is not intended to create this user prior to running the command, nor is there an option to e.g. define its name: https://docs.nextcloud.com/server/17/admin_manual/configuration_server/occ_command.html#command-line-installation-label

Damn thing.... workaround is a difficult thing. oc_admin is for security reasons created with a random password which is applied as one install step to config.php automatically. Since there is not even a default config.php available on fresh install, we cannot even pre-create the user with password... And even then, if I remember right, ncc maintenance:install simple creates a new user when already existing... although since it does not create it currently... further investigation required!

Jep, no change to use the command with a pre-created database user:

Error while trying to create admin user: Failed to connect to the database: An exception occurred in driver: SQLSTATE[HY000] [1045] Access denied for user 'oc_admin1'@'localhost' (using password: YES)

Nasty bug... we can of course do a complete manual install but that would be a VERY bad step back...

Still working with: https://download.nextcloud.com/server/releases/nextcloud-17.0.1.tar.bz2
So a bug introduced with Nextcloud 17.0.2.
PR up for workaround: #3278

Bug reported to Nextcloud repo: nextcloud/server#18513

• Identified harmful change with 17.0.2: nextcloud/server@f3ad49b
• Sadly we cannot fix this in code, since this would produce integrity check failure. We must wait for official fix.

Or make it a one-liner:

sed -i '/download\.nextcloud\.com/s/latest\.tar\.bz2/nextcloud-17.0.1.tar.bz2/' /DietPi/dietpi/dietpi-software

[Joulinar]

btw: I can confirm the one-liner workaround working 👍
