Please, do not delete the template when you open a new thread

Usually just plugin the USB cable and it should connect.

Here comes the template into game:
It asked for the systeminfo bundle.
Please attach it to your next post.

How did you install it? With the help of some guide, or an installer or just by hand?
Which linux distro?
