New VPN, Mint Can't get GUI installed

Aloha, I'm being dumb. I tried to move away from using PIA- private Internet access do to some suggestions. I bit the bullet and finally switched VPNs after ~5 years or so.

I know others may say it's dumb but I was going to try Proton VPN. On my phone, no issues. If I run the installers in Mint though, I can't seem to get it to install. Tried the Debian install, tried the Ubuntu install, but no luck. Specifically the command sudo apt install proton-vpn-gnome-desktop Will always return an unable to locate package, even while running from the same directory I run the wget commands and such from.

Is there something that you have seen that works well with this? I need to set that machine back up for a split tunnel for a couple specific apps and not others.
