Hi there,
I am just trying to start with the book, but am stuck at chapter 2.4 "Getting the project source code".
Before I started, I checked the book requirements (symfony book:check-requirements) and everything is good to go.
But when running symfony new --version=6.2-1 --book guestbook and getting to "Installing PHPUnit (this might take some time)" the operation is cancelled, indicating the error "Cannot open file 'install'".
Re-running with --debug does not reveal any additional information.

I am installing things locally on Ubuntu 22.04.2 LTS

Thanks in advance.
Regards,
Sebastian
