The problem you are seeing is related to network issues in WSL2 and unrelated to deal.II/candi. It just happens that the "git clone" command fails. If you google for "WSL git clone failure" you will find ample documentation and workarounds. For me it helped to adjust the MTU, but it might be different for you.
