I am tyring to build a Docker image for FRR using
https://github.com/FRRouting/frr/blob/master/docker/ubuntu20-ci/Dockerfile. When it gets to line 55, it fails on ./bootstrap/.sh. I have manually inspected the Dockerfile and it seems that the only thing that would write anything to /home/frr/frr is the libyang build. But that isn't producing any file by that name. I tried manually building libyang, too.
