Nimble seems to grab the package list from these 2 URLs:
1. https://raw.githubusercontent.com/nim-lang/packages/master/packages.json
2. https://nim-lang.org/nimble/packages.json

I'm experiencing some connectivity issues with the first URL so it uses the next URL as a fallback. The issue is that package list on the second URL is not updated, some of the packages (like `nimlangserver`, `happyx`, etc) are not found there - causing errors when I try to install/update them.
