Ci-dessous, une réponse en Anglais à ta question
"ADM is just the customization OS based on Linux Kernel, it's not totally same with Debian or Ubuntu.
It didn't support to install any modules/apps via SSH mode.
Ex: users can use apt/apt-get command to install any packages, including nano, from Ubuntu or Debian,
but ADM cannot support this, it's too dangerous for the system.
ADM can only allows installing app via apkg format that we defined in developer guidelines.
Please be understanding that ADM is linux-based OS, but not support all features of Linux.
ADM can use "vi", but "nano", and cannot install "nano" by the way user used in uBuntu or Debian."
