hi. can some confirm if there is an issue with monero cli? 'Fluorine Fermi' (v0.18.4.3-release) I execute transfer <addr> 1 and he ask to confirm and pressing y<cr> he stucks with showing y^M. any idea what could be the issue

Your terminal may not be sending the key codes monero expects. That'd be what libc expects really, this is using the standard lib IIRC.

Try another terminal, it'll likely work.

Or if you have several <cr> on your keyboard, they might be having different key codes.
