The SoB (DCO) check failed 85aa2ee0fa16c407524b9402e311aaa59973efc1 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.
