1 month ago To make sure the content data is fine, you can download the file from the browser.
You need to replace the ${CONTENT_ID} with the Id of the right version https://carla-assets.s3.us-east-005.backblazeb2.com/${CONTENT_ID}.tar.gz
You can look up the content id in https://github.com/carla-simulator/carla/blob/dev/Util/ContentVersions.txt
After that, you need to create a folder with the name "Content" and a "Carla" folder in it.
- path/to/carla
- Unreal
- CarlaUE4
- Content
- Carla
- Unreal
The content of the downloaded file need to be copied in the in the "Unreal/CarlaUE4/Content/Carla/" folder.
If you still have a problem after that, you can try delete everything in the "Build" folder, and install the dependencies again. "make PythonAPI" or "make launch"

Hi everyone!
CARLA version: Still try to get it running Platform/OS: Ubuntu 20.04 Problem you have experienced:
After a reinstallation of Carla, I tried to start Carla with "make launch", but unfortunately run into another error.
path to carsim uproject CarlaUE4.uproject Traceback (most recent call last): File "/home/user/UnrealEngine_4.26/Engine/Binaries/Linux/carla/Unreal/CarlaUE4/../../Util/BuildTools/enable_carsim_to_uproject.py", line 65, in <module> main() File "/home/user/UnrealEngine_4.26/Engine/Binaries/Linux/carla/Unreal/CarlaUE4/../../Util/BuildTools/enable_carsim_to_uproject.py", line 33, in main uproject_file = open(args.file, 'r') FileNotFoundError: [Errno 2] No such file or directory: 'CarlaUE4.uproject' make: *** [Util/BuildTools/Linux.mk:8: launch] Error 1Maybe this is due to the fact that I could not execute ./Update.sh to get the assets due to a certificate error. I checked before the file of Update.sh and the URL was according to #7192 the correct one (CONTENT_LINK=https://carla-assets.s3.us-east-005.backblazeb2.com/${CONTENT_ID}.tar.gz). I checked the internet and did, as someone proposed in #7192, copy the assets directly (git clone https://bitbucket.org/carla-simulator/carla-content Unreal/CarlaUE4/Content/Carla). This seemed to work fine, but probably it is now the source of the error.I hope someone can give me some advice here.
What you expected to happen: I would expect after a successful build of PythonAPI that Carla would open and I could run a simulation.
Other information (documentation you consulted, workarounds you tried): My system is not clean, there have been a local Carla installation before, which broke. Therefore I try to reinstall now thing, following the description in https://carla.readthedocs.io/en/latest/build_linux/.
I had before an error during the make PythonAPI, but could solve it with the help of the github community, see #8006
Thanks for your help.
