Hello Linux Geeksters. If the previous method for performing speedtests via commandline failed, use the instructions from this article.

In this article I will show you how to perform speedtests via the speedtest-cli tool. Since it depends on python only, this installation guide works on all the latest Debian/Ubuntu systems and derivates.
Follow this instructions exactly, in order to successfully install Speedtest Cli on Ubuntu, Linux Mint, Debian, Elementary OS and Pear OS:
If you don’t have any version of Python already installed on your system, here’s how to install Python 3.3 on Debian, Ubuntu and derivates.
Next, install the python-pip package, a tool for managing Python packages:
$ sudo apt-get install python-pip
Install the speedtest-cli via pip, and you’re done:
$ sudo pip install speedtest-cli
To perform speed tests, just open a terminal, type speedtest and hit enter.
