RPi5 + Ubuntu 24.04 + Hailo AI Hat: gst_parse_error: no element "hailonet"

I am running Ubuntu 24.04 on a RPi5 with the Hailo AI Hat. I followed the following guide to get it things to where I am:

https://ubuntu.com/blog/hackers-guide-to-the-raspberry-pi-ai-kit-on-ubuntu

However, when I try to run the example basic detection I get the following:

Hey @nat.todd ,

Welcome to the Hailo Community!

It looks like you might be missing the Hailo Gstreamer plugins that are included in the Tappas core installation.

To check if they’re installed, could you please run these commands:

gst-inspect-1.0 hailotools
gst-inspect-1.0 hailo

If you’re still having trouble, I recommend running the diagnostics tools described in this guide: hailo-rpi5-examples/doc/install-raspberry-pi5.md at main · hailo-ai/hailo-rpi5-examples · GitHub

Let me know if you have any other questions!
