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
# or
W: GPG error: http://apt.datadoghq.com unstable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 226AE980C7A7DA52

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 keyserver.ubuntu.com --recv-keys C7A7DA52

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.
