@enoch85 I think this is an issue from the Deck app.
We could either don't allow to install the Deck app during the nextcloud_install_production.sh script for now or use nextcloud_occ_no_check here:

vm/nextcloud-startup-script.sh

Line 416 in c6ab30e

nextcloud_occ user:delete "$NCADMIN"

another idea would be deinstalling the deck app if it is installed before deleting the user...

[szaimen]

This is actually a big problem because the startup script fails because of this... @enoch85 what do you think about my ideas how to solve this?

[silverdr]

This is actually a big problem because the startup script fails because of this...

Precisely. For now I can try w/o Deck but it seems like a rather important issue.

[szaimen]

the deck issue seems to be already fixed nextcloud/deck#2569 but as long as there is no new deck release, we have to workaround since the startup script will fail if deck is installed

[szaimen]

There was a new deck release. https://github.com/nextcloud/deck/releases/tag/v1.2.1
So I guess we only need to wait 1-2h until the new version is in the app store and then it should work again.

Thanks for debugging @szaimen
