I’ve pushed a lot of commits yesterday with different attempts to fix this. Strange thing is that when I’ve added a step with such a command before checkout:
mkdir ~/.ssh && touch ~/.ssh/known_hosts && ssh-keyscan github.com >> ~/.ssh/known_hosts
it’s output was:
# github.com SSH-2.0-babeld-76c80caa
# github.com SSH-2.0-babeld-76c80caa
no hostkey alg
