  1. thank you for this.
    It’s articles and pages just like this that make transitioning from msft to ubuntu that much easier. I appreciate this.

  2. Thank you! Worked perfectly. Other posts didn’t lay out as clearly the commands that needed to be run to successfully install libssel0.9.8. Once that worked everything ran smoothly.

  3. Thank you very much for this excellent explanation and helpful procedure. I am learning my way around Linux and really appreciate your willingness to share your knowledge.
