I searched Debian's packages and it looks like they've removed Nginx from the stable distribution (Jessie). It looks to be temporary as it's still in Sid, but I can't find any information on Debian's site. Does this indicate a problem with the previously available packages? From what's on my machine, the previously available version was 1.6.2.<p>Here are the search results, although they're liable to change when Nginx gets reintroduced:

No it hasn’t. It’s still listed at the link you posted, and I see no evidence that it was ever removed at <a href="https://tracker.debian.org/pkg/nginx" rel="nofollow">https://tracker.debian.org/pkg/nginx</a> (if it had been removed, there would be a news item there with a reason). If you saw it missing on packages.debian.org, that must have just been a temporary website glitch.
Some people may find this useful in the future: <a href="http://nginx.org/en/linux_packages.html" rel="nofollow">http://nginx.org/en/linux_packages.html</a><p>Besides stable and mainline versions of nginx it also provides other packages maintained by nginx such as nginx-nr-agent.
