The SoB (DCO) check failed 4081bde7c7e534b0ab7d265c2d508ee7c7e07710 Expected "Jian Zhu <[email protected]>", but got "zhujian <[email protected]>". 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.
