Error on launching on Ubuntu 16.04

I searched here and didn’t find the same error I’m getting on launching the engine on Linux.

On launching from terminal, I get the following error:

./UE4Editor: symbol lookup error: path/to/engine/UnrealEngine/Engine/Binaries/Linux/libUE4Editor-Kismet.so: undefined symbol: _ZN26FGraphEditorDragDropAction9ConstructEv

Anyone knows what is going on?

Your google-fu is not so strong:

Not sure if some of the fixes listed there are still valid though.

Also why 4.17? we are on 4.19.1 now for most cases

I found this thread on google, but the issue reported their is different than mine.
4.17 because of compatibility with AirSim
