Setup
Describe the setup you are using to run CARLA along with its version:

• CARLA version: 0.10.0
• Platform: Ubuntu 20.04
• Python version: 3.8.10
• GPU: ...
• GPU Drivers: ...

Describe the bug
I modified Unreal/CMakeLists.txt, add "-pak" in command:
COMMAND
${CARLA_UE_UAT_COMMAND_PREFIX}
BuildCookRun
-project=${CARLA_UE_PROJECT_PATH}
-nocompileeditor
-nop4
-cook
-stage
-archive
-package
-iterate
-clientconfig=${UE_BUILD_CONFIGURATION}
-TargetPlatform=${UE_SYSTEM_NAME}
-Platform=${UE_SYSTEM_NAME}
-prereqs
-build
-pak
-stagingdirectory=${CARLA_PACKAGE_STAGING_PATH}
-archivedirectory=${CARLA_PACKAGE_ARCHIVE_PATH}

after "cmake --build Build --target package" successful, with command ./CarlaUnreal.sh ,it worked, but when I use command "python config.py -l", error occured: filesystem error: in create_directories: Permission denied ["/home/xxx/carlaCache/0.10.0/../../../CarlaUnreal"], The correct output should list the available maps.

Steps to reproduce
1.modify Unreal/CMakeLists.txt, add "-pak" to command ${CARLA_UE_UAT_COMMAND_PREFIX}
2.cmake --build Build --target package, get the shipping Carla
3../CarlaUnreal.sh
4.python config.py -l

Expected behavior
after python config.py -l, it should list the available maps

Logs
$ python config.py -l
filesystem error: in create_directories: Permission denied ["/home/xxx/carlaCache/0.10.0/../../../CarlaUnreal"]

An error also occurred when running "python manual_control.py"

I think there's an error in mount point parsing, which is why the returned assets always include ../../../.

[Uchiha-ciel]

After analysis, the path returned by the server is ../../../CarlaUnreal/Content/Carla/Maps/Nav/Town10HD_Opt.bin. The presence of the mount point prefix ../../../ causes incorrect final path parsing. The issue lies in the get_required_files and request_file methods in CarlaServer.cpp. Is this a bug?
