the last line is german for
E: package grails-ppa could not be found. 

what should i do better? 

A:

The maintainer of that ppa has moved on to create http://gvmtool.net/ which is a much more robust solution which also supports Groovy, Griffon, and other technologies.  We haven't yet updated the web site to make that more clear, but GVM is definitely the way to go.
