I am also seeing the same errors. There appears to be a few places online where others are also seeing the errors. I’ve reverted to using 5.4.4 for now until there is more info. I need the engine to compile without problems and also nightly builds. > [@UE 5.5 Source Linux Compilation Errors](https://forums.unrealengine.com/t/ue-5-5-source-linux-compilation-errors/2148769): > > Compiling 5.5 from source throwing these errors. Any help would be appreciated. Also using Ubuntu No errors or warnings while generating project files (tried the suggestion here but either I’ve applied the fix wrongly or its not working). [AUR (en) - unreal-engine](https://aur.archlinux.org/packages/unreal-engine) ( See KarthikJay comment) **I am not at all an expert in building unreal** but I wonder if the ubasessionserver might be the issue. All the thrown errors do not have (ubs disabled) next to them. Post here how to turn the session server off - though I’ve not yet tried this. Might try overnight. > **[Disable UbaSessionServer (UBA) | Community tutorial](https://dev.epicgames.com/community/learning/tutorials/9dv9/unreal-engine-disable-ubasessionserver-uba)** > > How to disable UbaSessionServer (UBA) / Как отключить UbaSessionServer (UBA) --- _[View the full topic](https://forums.unrealengine.com/t/cant-build-5-5-1-from-source-on-linux-mint-ubuntu-based/2225077)._
