Change password's administrator in CLI

[Florian Coste]

Hi,

I am back with Lubuntu since I installed it on a hardware board
(ODROID-C1). Actually I am using Lubuntu via ssh tunnel.

I do not have an authentication by private/public key yet, because I would
like to change my password's administrator. Indeed I didn't install Lubuntu
from scratch, but I used a specific image for my board (download in the
repo of hardkernel, creator of the board). And so, I couldn't choose the
password.

Do you know how I can change it ? Is it possible to do it with SSH ?

Thank you
