I just rebuilt my Nextcloud instance and accidentally installed the latest version 30. Unfortunately, Collabora Online - Built-in CODE Server (ARM64) does not work as desired. Therefore I would like to downgrade to version 29, which previously worked without any problems for me.
I understand that Nextcloud 30 is still very new and may still contain bugs. Since I urgently need Collabora, I currently see no other option than downgrading.
Do any of you have experience with such a downgrade from 30 to 29? Are there any instructions or specific steps I need to follow?
I tried to install the app as usual, but when I clicked “Download and Activate” a small red error message appeared: **“There was an error with the request. Cannot proceed.” nc30collabora-built-in
