I created a blank project and tried building the Linux server, but an error I’ve never seen before occurred.
I Clean Engine Intermediate and Rebuild but error
BUILD FAILED: AddBuildProductsFromManifest: C:\Users\fatma\Documents\Unreal Projects\MyProject\Binaries\Linux\MyProjectServer.sym was in manifest “E:\UnrealEngine\Engine\Intermediate\Build\Manifest-2-MyProjectServer-Linux-Development.xml” but could not be found.
Did you find any solution for this error?
Same issue when I am trying to package my project from windows to linux on UE5.5. This exact same project used to package correctly 2 months ago
Did you find a solution ? thank you 
Some problem, did you find a solution?
same issue here. does anyone have a solution to this?
Been using Linux Servers since Unreal 4.7.
Doesn’t seem to cause any crash.
Same issue for me, anyone find a solution?
Fixed it by going to my source build folder and running Setup.bat → GenerateProjectFiles.bat → Full rebuild.
Have similar issue.
it seems that full project rebuild doesn’t help, but I have vanilla EGS version.
Have this error when I try to compile “Game” configuration for Linux from project sources:
UbaSessionServer - ASSERT: Unhandled Exception (Code: 0xc0000005)
Callstack:
ntdll.dll:+0x73dc6
ntdll.dll: +0x74326…
Will try to compile engine from sources…
(Sorry about the caps, I do not feel like typing again)
FIXED after 20 hours of sluething!!!
TO ANYBODY GETTING THIS ISSUE, I HAVE SOLVED IT! FIRST, YOU HAVE TO DOWNLOAD the LLVM STABLE VERSION FROM THEIR GITHUB PAGE. WHEN SETTING UP THE INSTALLATION, SET IT TO ADD TO the ENVIRONMENT VARIABLES FOR X USERS. THEN, MAKE SURE IT IS IN THE PATH LOCATION OF SYSTEM VARIABLES. YOU ALSO HAVE TO PATCH THE CLANG INSTALLATION, AS IT IS MISSING COMPONENTS.
STEP 1:
Download a stable version of Mingw64 for Windows and copy the files llvm-objcopy or objcopy, libwinthread-1.dll, and llvm-strip.exe to your clang \bin folder (x64 one, not the other).
STEP 2:
Next, you have to open a new version of the command prompt and run the following script in your \Binaries\Linux folder of your project:
llvm-objcopy.exe --only-keep-debug Project NameServer project NameServer.sym
NOTES:
Clang and LLVm must be in different folders than the UE5s. I left them in their default download locations.
Server is the name of my build target.
If you get issues with what I said above, the Packaging fails with a manifest error. Unreal expects the projectname_Server.sym file, but it’s missing. You need to fix your clang path to have llvm-objcopy.exe and install LLVM for Windows x64, and generate a .sym file in your project’s Linux binaries folder using the script
