Upgrade error: here is no table with name “nextcloud.oc_openregister_objects” in the schema

[rcfa]

The latest update forces an upgrade which results in this error message in the web interface:

Update to 30.0.1

Exception: Database error when running migration 1Date20241019205009 for app openregister There is no table with name “nextcloud.oc_openregister_objects” in the schema.

The update was unsuccessful. Please report this issue to the [Nextcloud community](https://github.com/nextcloud/server/issues).

if I use occ, then I get this, which is essentially the same:

# occ upgrade           
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade

Hi @rcfa,

Thank you for filing this issue. We are looking into it.

I have one question on this subject: This app has not reached a stable status yet, and therefore migrations can change. Does this error persist if you remove the app and reinstall it?

[rcfa]

I tried to remove it both from the web UI and with the occ command, and reinstall it, with similar/same results:

# occ app:remove openregister
openregister is not installed
                                                                                                                                    
# occ app:install openregister
Error: Database error when running migration 1Date20241019205009 for app openregister
There is no table with name "nextcloud.oc_openregister_objects" in the schema.

So while I can remove the app, I can’t remove whatever leads to the error upon upgrade/install
