The issue you are facing:

Multiple ImagickExceptions.
I’m not sure if it is caused by a “to old” GS oder a mistakt in the setup

ghostview ist installed (v9.26), as mentioned here

Is this the first time you’ve seen this error? (Y/N):Y

The output of your Nextcloud log in Admin > Logging:

Have you managed with this error ? I faced with the same issue. But can’t find solution.

Ok, I found solution.

In my case apache couldn’t access the ghostscript path. It’s located in /usr/local/bin/gs and it should be symlinked to /usr/bin/gs by running this command:

ln -s /usr/local/bin/gs /usr/bin/gs.
