These files are based on cz-guardian/fedora-deepin and Arch packages. As of Fedora 30, Deepin Desktop can be installed directly from Fedora repo.
sudo dnf install @deepin-desktop
sudo dnf install xorg-x11-server-Xorg # (if you don't have other desktop installed before)
sudo dnf install http://download1.rpmfusion.org/free/fedora/releases/$(rpm -E %fedora)/Everything/$(uname -i)/os/Packages/r/rpmfusion-free-release-$(rpm -E %fedora)-1.noarch.rpm # Optional, only needed for the multi-media packages.
sudo dnf install deepin-movie deepin-music deepin-screen-recorder deepin-voice-recorder # (need rpmfusion repository)
sudo systemctl disable gdm.service && sudo systemctl enable lightdm.service # (optional, gdm also works with Deepin Desktop)
After this is done, simply reboot into your new nice environment.
