Repro

1. Install agent
2. Remove or move /etc/dd-agent/supervisor_ddagent.conf away
3. Restart supervisord
4. Stop agent with sudo service datadog-agent stop

Here's a patch to unstuck apt-get:

wget -O - https://raw.github.com/gist/2890110/e44a07a62f787405f23163daf13743231488c98e/datadog-agent.diff 2> /dev/null | sudo patch /etc/init.d/datadog-agent

Same issue:
Errors were encountered while processing:
datadog-agent-base
E: Sub-process /usr/bin/dpkg returned an error code (1)

Patch does not work anymore.

Was able to solve with:
mv /etc/init.d/datadog-agent.orig /etc/init.d/datadog-agent

Pleaser reopen this bug, moving the file doesn't solve a product bug, see #1130

Maybe is different because in my case removing the file didn't solve the problem.
