How to upgrade from 3.0.4 on Debian and Ubuntu

When we released datadog-agent 3.0.4 we made a mistake and messed up the version dependency between packages. As a result, whenever you run apt-get upgrade or apt-get dist-upgrade and 3.0.4 is installed you may get the following error:

E: Couldn't configure pre-depend datadog-agent-base for datadog-agent, probably a dependency cycle.

If that's the case, don't panic: there is a simple fix. Simply run:

sudo apt-get update
sudo apt-get remove datadog-agent
sudo apt-get install datadog-agent

to get the new versions up-and-running.
