I am watching sample metadata tutorial. I downloaded the metadata using URL but wanted to practice using wget or curl. I do not know the difference and do not know why both not working as in picture

As long as I can see, you haven't used neither wget nor curl. You can try adding one of them before pasting the link in terminal.
Also, please copy and paste the code instead of sending screenshot of it since it is a text.
I hope this helps...

No, I mean I thought you did already, what happened to that installation? It may already be installed? Are you using a new computer? Did something happen to your old computer? Is this groundhog's day? Up is down and down is up? Ben

They need to be installed at the base, do not install them inside the conda environment. Ben

It is simply at terminal, when you open it, before you launch qiime2, you should install home-brew and then the wget package there. Ben
