Zdravím.
Neví někdo, jak ho změnít?
There is no working 'passwd'.
The 'passwd' command changes passwords for user accounts.
With LibreELEC it is not possible to change the system password
SSH is included only as a last support resort. SSH is off by default.
Most users never need SSH and need help using it so we need a default
password. If you need to keep SSH always on then this is unsupported
but can be secured with certificates.
