@dobey Thanks for your advice. I've used these two commands:
echo "export PATH=$HOME/.local/bin:$PATH" >> ~/.bashrc
export PATH="$HOME/.local/bin:$PATH"
Now I execute the terminal command clickable, but it seems, that docker is required:
clickable
The command "docker" does not exist on this system, please install it for clickable to work properly"
Thus I tried the following command:
sudo apt-get install docker
[sudo] password for marc:

Unfortunately this doesn't help. I get the same error. Any idea?
Edit: Ok, It seems, that sudo apt-get install docke' is not sufficient. I could resulve the issue with sudo apt-get install docker.io.
