I can’t seem to launch Unreal on ubuntu 24.04.1 LTS

Trying to run Unreal engine per the instructions

I extracted the zip file to ~/Documents/Linux_Unreald_Engine_5.5.1
I entered the directory ~/Documents/Linux_Unreal_Engine_5.5.1/Engine/Binaries/Linux and run ./UnrealEditor and get the following error

./UnrealEditor: error while loading shared libraries: libUnrealEditor-AddContentDialog.so: cannot open shared object file: No such file or directory

Using “find”, I can’t locate any file with that name name from the Linux_Unreal_Engine_5.5.1 directory and down.

Any advice or tips welcome.

Hello there @Porchiges2! Let’s see what we can do here:

Your issue has been encountered in other community threads, the most succesful solution was to upgrade your video drivers to their latest version, as old drivers were clashing with UE. You can check further details here:

I’ve tried installing AMDs drivers, however still getting the same error message

./UnrealEditor: error while loading shared libraries: libUnrealEditor-AddContentDialog.so: cannot open shared object file: No such file or directory

I’m not sure if I’ve installed the drivers correctly. Checking I see this:

sudo lshw -c video

Any additional advice or direction is appreciated :pray:

I’ve circled back to this, seems like no one else was interested in the topic, but incase someone in the future find this;

My original installation of Ubuntu 24.04 was using ZFS. I’ve recently re-installed Ubuntu 24.04.01 with the default file system.

I then installed the latest version of Unreal Engine for linux and it seems to be working now.

I’m not sure if it was ZFS or the previous version of Unreal causing the issue, but everything is working now.
