New Version NCP 1.54.2 is displayed, but no update possible

My NCP interface and SSH login show me a new version of NextCloudPi (1.54.2). My ncp is currently running on 1.54.0.
When I initiate an update in NCP, this is not carried out.

Is there perhaps no update to 1.54.2, as there is only version 1.54.0 on Github?

Briefly about myself, I have only been a NextCloudPi user for 1 week and am not very familiar with Linux. Nevertheless, I got ncp up and running. A nice project :wink:
