chce dockera dziwny błąd

Podczas wykonywania skryptu na Mikrus4.0 pojawił się błąd, tak jakby otworzyło nową sesję? Wykonane polecenia:

# docker

Command 'docker' not found, but can be installed with:

apt install docker.io

tutaj skrypt niby skończył (w rzeczywistości to nie) wykonuję polecenie docker dla sprawdzenia:

# docker

Usage:  docker [OPTIONS] COMMAND
...
Run 'docker COMMAND --help' for more information on a command.
