Not able to install ProtonVPN

Question

I am trying to install protonVPN but I am getting this error. The file is located in my downloads folder and the filename is correct. I am following the instructions on the protonmail website. Below are my results. What am I missing?

Thanks.

ava@Earth:~/Downloads$ ls
protonvpn-stable-release_1.0.1-1_all.deb
ava@Earth:~/Downloads$ sudo apt-get install protonvpn-stable-release_1.0.1-1_all.deb

Answer 1

Have you tried to install it manually? If not try downloading the Debian package ProtonVPN and then use dpkg:

sudo dpkg -i protonvpn-stable-release_1.0.0-1_all.deb

If dpkg is complaining about missing dependencies, then use apt-get -f install after running dpkg, that is the best advice I can give you, it did not work for me though, but maybe it will help you?
