Recreating Protonmail VPN

[msh8er]

I had PM VPN using Win10 until about two weeks ago, when I decided I'd learned enough about Ubuntu over the years to rid myself of Bill Gates and MS.
I had all of the pieces together to create USB Ubuntu 22.04. Pushed the button and wrote U 22.04 all over my hard drive. I finally had to give up on recovering my former PM account, so I've created a new PM account, and am trying to do what should be a stone cold simple install.
What is going on here? It looks to me as if I downloaded the package I needed, but then it says "not so fast".

Geeezzz. So many messages meaningful to the elite few.
I found where I needed to load the missing package. I may go back to super Suduko or whatever.
