@Tanner_Sutherlin Hi and welcome to the community.
I think I have seen the before ...
Did you have a previous version of elastic agent on the system? Before you started this at the top of your post?
Either way...
If you have it installed please reload the systems
sudo /bin/systemctl daemon-reload
I would remove via the package.
Then I would check to see if
/opt/Elastic/Agent/elastic-agent is still there
if so run
sudo /opt/Elastic/Agent/elastic-agent uninstall
Then I would install with the tar.gz
and try again
if it fails run
sudo /bin/systemctl daemon-reload
then try again.
Where the agent runs from has been moved... I think you have an old sym link
This might help same error I helped debugg a bit back
