Development

Just go on this thread.
Last versions are posted here in .deb format or archive. Just download it and … well double click
or
dpkg -i unity-editor-[xxxxxxversion]
You have too options :
1 – OpenJDK. Very compatible, Free
To have the available versions : sudo apt search openjdk
As an example, sudo apt install -y openjdk-11-jre will give you the last runtime (execute .jar softwares) and sudo apt install openjdk-11-jdk will give you the development kit.
1 – Oracle Java. Kind of Open Source but you have to pay to publish softwares.
sudo add-apt-repository -y ppa:linuxuprising/java
Then you can install it the same way you install OpenJdk. sudo apt install -y oracle-java11-installer
First, make sure you’re registered. Here are the instructions.
Login on github.com
Now go https://github.com/EpicGames/UnrealEngine/
Click Clone or Download button. 
Download the .zip and unpack it. Right-click and open a terminal in the folder you just uncompressed. Generate the project files ./GenerateProjectFiles.sh then make
add the dependencies ./Setup.sh
Now, you can cd Engine/Binaries/Linux/ then ./UE4Editor
You may reach the Max Open Files limit when compiling shaders, or computing lightmaps. A very “unpleasant” problem, not only in Unreal Engine. To fix this once and for all on your system, just execute these two commands :
For graphical process :
echo "DefaultLimitNOFILE=65535" | sudo tee -a /etc/systemd/user.conf && echo "DefaultLimitNOFILE=65535" | sudo tee -a /etc/systemd/system.conf
then for non-graphical process (replace [user] with your user) :
echo "[user] hard nofile 65535" | sudo tee -a /etc/security/limits.conf && echo "[user] soft nofile 65535" | sudo tee -a /etc/security/limits.conf
Now re-connect your session (or reboot) and enjoy your new limit 😉👍
Bonjour comment faire pour l'installer sur fedora 30.
Fedora a le magasin d'applications de gnome et pas mal de dépôts en plus des Flatpaks. https://docs.fedoraproject.org/fr/quick-docs/finding-and-installing-linux-applications/
