Mmctl error after upgrading 6.3 ESR

Hello All!
I have an error after upgrading to version 6.3 ESR I want to run command “./mmctl license remove” and appear “Error: cannot read user credentials, maybe you need to use login first: stat /root/.config/mmctl/config: no such file or directory”.
What can I do to fix the error?

I solved, use --local argument, before modify mattermsot config json “EnableLocalMode=true;”

Congratulations and thank you very much for the information.
