I'm trying to install some debian packages from http://playdeb.net and the links do nothing. I've tried chrome, chromium, and firefox. Chrome and chromium just show blank screens while firefox says "The address wasn't understood". I've used playdeb in both Mint 17.3, 18, 18.1, 18.2 as well as Ubuntu 16.4, and 17.04 without issue. This is my first attempt on using them in Elementary. Am I missing something?
