The SoB (DCO) check failed 9713b674e569848e0b4f96477b55e41c3b93a14d The sign-off is missing. What should I do to fix it ? All proposed commits should include a Signed-off-by: <your-name> <your-email-address> line in their commit message. This is most conveniently done by using --signoff (-s) when running git commit.
