OS Agent Won't Load After Download

I am using Debian/Linux in a pc. I have downloaded the file several times using
root@MINIPC:~# gdebi //github.com/home-assistant/os-agent/releases/tag/1.2.2/os-agent_1.2.2_linux_x86_64.deb

When I attempt to load it using the command below I get this message.

root@MINIPC:~# dpkg -i os-agent_1.2.2_linux_x86_64.deb

dpkg-deb: error: ‘os-agent_1.2.2_linux_x86_64.deb’ is not a Debian format archive
dpkg: error processing archive os-agent_1.2.2_linux_x86_64.deb (–install):
dpkg-deb --control subprocess returned error exit status 2
Errors were encountered while processing:
os-agent_1.2.2_linux_x86_64.deb
root@MINIPC:~#

Any ideas brainiacs?

That seems wrong (or, at least, I don’t know what it does).
os-agent_1.2.2_linux_x86_64.deb should be ~2.5MB. Is it?

Just download the deb from https://github.com/home-assistant/os-agent/releases/tag/1.2.2/os-agent_1.2.2_linux_x86_64.deb and install it.
