No update anymore

Hi everyone.

A few weeks ago, I have an update problem with my nextcloud (it was blocked at step 3 during process and always says “Step 3 is currently in process. Please reload this page later” when I try to ipdate.
I resolved it with deleting *.step files (see Update stuck: Step 3 is currently in process. Please reload this page later).

But since, when I ask to nextcloud to upgrade via built-in updater, it says no update availlable (I’m sure there is an update because I’m with the 23.0.12 version). And it the same things with the terminal.

What can I do ?
Thank you

It would help to know what type of installation you have.

It’s install on a raspberry pie 4.
I’m using Dietpi as OS.
Thank you
