Welcome to the community! Please read #start-here when you have the opportunity.
The discussion.fedoraproject.org site is a user community, not Fedora developer community. And in the “Ask in English” category, many of us will struggle with being able to read the message on your screenshot. Please provide the translation so that more of the community can see the nature of your install problem.
Fortunately you do note that a bug has already been filed, so the developers will be aware.
