I have not needed to root android in years. Can you share why you need this? There has to be a better way.

Read http://www.androidpolice.com/2016/12/24/how-to-follow-the-new-lineage-os-online/ about what phones are supported and the benefits. It will by default be rooted.

Remember I already know what rooting is. Here I don't need it since all I ever needed was to allow third party apps. Some folk go get a root program since they didn't know a setting. Shame about that.
