Hey Gary, if you already have the News Skill on your device, your best bet is to use git to checkout the branch you want. In this case:

cd /opt/mycroft/skills/mycroft-npr-news.mycroftai
git checkout bugfix/rm-curl

I don't believe that MSM currently has the ability to parse the url and do this automatically. It's expecting the base url of the repo only - ie msm install https://github.com/MycroftAI/skill-npr-news
