Tis is my first post and I hope I’m right her.
I tried to update my NextcloudPi from v1.46.10 to v1.47.0 via SSH. The update aborted with an error. The following message was displayed:
pi@nextcloudpi:~ $ sudo ncp-update

Error while applying update 1.47.0. Exiting…
The same happens when trying to start ncp-update via the web-gui.
Is there a solution to update the ncp anyway?
Thank you for your help!
