System repair with a lot of messages

Hello community, I´m very new here and not so experienced with home assistant, so I hope you can help me.
Since yesterday I got a lot of messages - see picture

I can´t run the two updates:

Home Assistant Core
Installierte Version - 2023.3.1
Neueste Version - 2023.3.2

and

Home Assistant Supervisor
Installierte Version - 2023.01.1
Neueste Version - 2023.03.1

HA runs on a synology docker-container.

Can anybody help me to solve?

Kind regards.

Check for space issues (too little space left), like trying to do a backup before update to be downloaded and installed.

While I’m not too familiar with German or some of the other EU languages, it certainly looks like some of those messages are related to the system itself having trouble.

I’ve tried to clean up before update.
Doesn’t help.

Installation of HA Supervisor doesn’t start… Unfortunately.

The update won’t occur until you fix those issues, I suspect.

@daywalker03 I assume you´re right - so I just have to find the reason…
