You should follow the official instructions instead (use xcaddy):

Thank you. I started following that.
The requirements state this:
Requirements:

Go installed (see above)
Make sure xcaddy is in your PATH

And “xcaddy” is linked, but not to instructions of how to do that. How do I add xcaddy to my PATH in unbuntu?

That’s more of a “how do I use my computer” kind of question, honestly. There are countless guides on the internet that can explain that for you.

Typically you’d move the binary to /usr/local/bin which is one of the various directories that are in your PATH by default:

Thank you for your help. I understand PATH now. I had used it quite a bit in Windows, but am a complete newb in linux. So I used curl to download https://github.com/caddyserver/xcaddy/releases/download/v0.1.6/xcaddy_0.1.6_linux_amd64.tar.gz and moved it to /usr/local/bin. I tried the xcaddy command and it didn’t work. Then I opened up ~/.profile and added this line to the end export PATH=$PATH:/usr/local/bin. I tried the xcaddy command and it still didn’t work. I also rebooted the linux server after each step.
What am I missing?

You need to give the xcaddy binary executable permissions. You can do that with chmod +x <file>
