пытаюсь установить NX Client. Что подразумевается под вторым пунктом??

DEB version

    *1)Download the DEB
    *2) Change your working directory to the location where you saved the package and install it by running from a console:

        # sudo dpkg -i nxclient_3.3.0-6_x86_64.deb

If you don't have the sudo utility installed, log on as superuser ("root") and run the commands without sudo.
