  1. Great tutorial. I am a new Ubuntu user. Work in a company that doesn’t want to “throw money” (managent saying) into IT. I am an sysadmin and had to choose between better hardware specs, but without W10, and lower hardware specs with W10. I choose better hardware specs and Ubuntu :-). My favourite browser is Palemoon, and you have halped me a lot.

  2. Nice work! Thank you. Pale Moon installed on Ubuntu 18.04 with no problems.
