I need to find out what file is creating /etc/apt/sources.list.d/droplet-agent.list which I no longer need in my Ubuntu Digital Open VPS. I tried doing apt-file search /etc/apt/sources.list.d/droplet-agent.list but even with all repositories up-to-date, I get nothing at all from apt-file.
I tried sudo grep -R "/etc/apt/sources.list.d/droplet-agent.list" /etc but I get a lot of "no such file or directories.

How am I going to figure out what is causing the file droplet-agent.list to be created in the /etc/apt/sources.list.d/ directory? During the past couple of months, I tried to get the Digital Ocean droplet agent installed in my VPS server, but I decided I do not need it anymore and I am trying to get my VPS to stop adding the droplet-agent.list repository.
