You get this error when p2 can't find the update site to install. Looks like the url that youa re using is correct, so the problem is one of two things:

1. Temporary network issues. Try again and it might work
2. A firewall on your side. If so, set your network proxies at Preferences -> General -> Network connections

As a side note, the update site is an old style update site (ie- pre-3.4 and does have proper metadata). You should encourage the maintainers of this plugin to update to a modern update site.
