can't install nordvpn on ubuntu 20.04

today I removed nordvpn and tried to install it again, I followed all steps that mentioned in the official website and still can't get it work.

sudo dpkg -i ./nordvpn-release_1.0.0_all.deb

sudo apt update

sudo apt install nordvpn

Solution 1:

If you downloaded the .deb via a browser it should be in \home\<user name>\Downloads, cd to that location:

cd /path/
sudo dpkg -i <name of file>.deb

If it shows broken packages or missing dependancies follow on-screen instructions.

In response to below comments, seems like the .deb file just adds a repository but does not install the nordvpn package.So you need to run

sudo apt-get update
sudo apt-get install nordvpn

as well to actually install it which wasn't clear to me.

Check for these two lines for a successful addition when apt update is run:

Get: https://repo.nordvpn.com/deb/nordvpn/debian stable/main amd64 Packages [3,298 B]
Get: https://repo.nordvpn.com/deb/nordvpn/debian stable/main i386 Packages [3,298 B]

Seems like the .deb failed to add the contents to /etc/apt/sources.list.d/nordvpn.list, so here are they

deb [arch=amd64] http://repo.nordvpn.com/deb/nordvpn/debian stable main
deb [arch=i386 ] http://repo.nordvpn.com/deb/nordvpn/debian stable main 

Steps:

cd /etc/apt/sources.list.d/
sudo nano nordvpn.list

Add the above contents exactly as they are without any "#" at start or end in a blank line.

Runsudo apt update then and sudo apt install nordvpn
