Debian Ubuntu package: Expired Signature

Issue

Starting on March 15, 2014, when running:

# apt-get update

you may encounter the following error message:

GPG error: http://apt.datadoghq.com unstable Release: The following
signatures were invalid: KEYEXPIRED 1394856986 KEYEXPIRED 1394856986
KEYEXPIRED 1394856986

Cause

The key that we used to sign our Agent deb package expired on March 15th, 2014.

Who is impacted?

If you installed the Datadog Agent on a Ubuntu/Debian system before March 15th, 2014, you are likely to be encountering this issue.

How do I fix it?

To fix this issue, you would need to add the new key we use to sign our packages. You can do this by running

$ sudo apt-key adv --keyserver http://keyserver.ubuntu.com --recv-keys C7A7DA52

(or sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C7A7DA52 on some versions)

Is this urgent?

You will only encounter this issue when you try to update (or re-install) the Agent. Therefore, it is not urgent and you can update the key when you plan to update the Agent.
