turns out I forgot to add "become" to run as superuser. I can close this issue, however, I would like to suggest to add more meaningful error messages to the output if possible, shall I modify this issue or close and reopen a different one?

Thanks.

I'm wondering whether nmcli is giving a better/proper error message that we're ignoring for some reason.

hi @felixfontein, I checked and it does give you more details, it says "insufficient privileges".
