Hi @al3x-lm, welcome to the community!

I’m not sure we have ever tried to build Cesium for Unreal on docker, so we might be limited in our ability to help. But perhaps you can share the steps that you took to get to this point?

We have a Developer Setup guide for Linux users – though it’s possible that you’ve seen that already. Even so, let us know what steps you did leading up to the error so we can better understand your process. Thanks!

The issue was due my .git directory was not passed to the container, looks like it was causing lfs files to error.
