Re: installing from source
Then, I strongly advise that you do NOT install from source. It really is the most difficult way to install an app, requires the most work, and encounters the most problems.
as a none programmer who doesn't desire to alter the code in any way?
There are other ways to get more recent app versions than using the repositories and one of them is using PPAs.
Really, you should only resort to installing from source if there is no other way to get the version of the app you want.
Ubuntu 16.10 Mate, Mint 18 Mate; MS Win 8.1, MS Win10 Pro.
