Hi... The same issue had occurred with the rpm of 5.7.5-2 ( http://www.valentina-db.com/en/discussions/install-of-5-7-5-2-rpm-fails-on-fedora-21-workstation ) . It was resolved shortly after my report. I hope having this one sorted out as quick :

On Ferora 21 Workstation when trying to install vstudio-5.8.0-2.x86_64 version of Studio :

Transaction check error:
file / from install of vstudio-5.8.0-2.x86_64 conflicts with file from package filesystem-3.2-28.fc21.x86_64
