I installed youtube-dl from the 17.04 package repositories. It currently ships version
2017.03.10. However, youtube-dl is one of these packages that are updated very frequently (as of writing this post it is version
2017.04.11) and quite often you actually need to have the latest version for it to work with the latest changes done by YouTube.
For packages that change very frequently — like youtube-dl — what is the preferred and recommended installation method?
