It appears that you mixed older Go version with new one in same path.
Please try to remove the '/usr/local/go' and reinstall again.

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.
