Hello Ingo,
Here https://stackoverflow.com/questions/35962861/how-to-fix-unable-to-create-pristine-install-stream it says that manually creating a tmp folder in the <your app>\.svn\ folder might help. Can you try that?
Regards,
Paul
Are you able to uodate the repository or do you get then the same error?
I sometimes get this error due to poor internet connection, if I close the error and try again for couple of times it works as expected. Did you try to commit again? Check you internet connection and try to commit again.
I have updated the medix modeler version and now I got following error message:
SharpSvn.SvnSystemException: Commit failed (details follow): ---> SharpSvn.SvnSystemException: Unable to create pristine install stream ---> SharpSvn.SvnSystemException: Das System kann den angegebenen Pfad nicht finden.
