  1. After installing Ubuntu 18.04 LTS, only Ubuntu’s main repository is available. I had to add restricted, universe, and multiverse repositories to be able to complete the install as you have it described.

    Thanks for the great write-up!

  2. Great. One of the few instructions that are without mistakes. I do not find it very often. Keep it up and thanks again.

  3. Tried these directions on two different VMs.

    This did not work until I entered sudo a2dissite 000-default.conf

    Thanks for the guide.
