CARLA version: 0.10.0 + UE 5.5
Platform/OS: Ubuntu 22.04
Problem you have experienced: Could not find Unreal Engine clang sysroot.
What you expected to happen: The setup should finish without errors
Steps to reproduce:
cd CarlaUE5
sudo -E env GIT_LOCAL_CREDENTIALS=github_username@github_token ./CarlaSetup.sh

Can you verify if UE5 is properly built? Try running ./Setup.sh && ./GenerateProjectFiles.sh && make in the unreal engine folder (it seems to be /home/ubuntu/CarlaUE5). Maybe a previous setup failed and left UE5 in a partially built state. I will add an argument to CarlaSetup to handle this case later.

The Setup.sh and the GenerateProjectFile.sh do not exist (yet?).

You don't have the correct path in CARLA_UNREAL_ENGINE_PATH. Update the variable to point to where you UE5 resides. It might be in ../UnrealEngine5_carla relative to CARLA's directory. If this path doesn't exist, delete the environment variable from ~/.bashrc and rerun setup.
