[seankhliao]

did you completely remove the previous installation before installing the current version?

[pjmlp]

You're right, it was my mistake when installing the RC, not everything was cleaned out.

It works as expected.

Closing the issue.

@pjmlp How did you completely clean the old installation

@pjmlp How did you completely clean the old installation

I just ran rm -rf /usr/local/go on Linux
