CSVImport Module: Upgrade fails

Dear all,

I would like to use CSVImport module to have the possibility to import items, media and metadata for media. I tried to use the CSVImport module forked by Daniel-KM.
I was using before the standard module https://github.com/omeka-s-modules/CSVImport/tree/master

When I’m trying to install this version CSVImport , there is only an upgrade button in the module folder. If I click upgrade, there is only this message “Omeka S encounterd an error”.

Can anyone give me advice what I can do to fix this.
System information: Omeka S version 1.1.1 and Ubuntu 4.1.5-22.

Thank you very much for your help.
Best wishes,
Rolf
