I have installed an OpenVPN server on a Debian Linux server. I have a client.ovpn file for my VPN server. How do I use it with Network Manager GUI? Is it possible to install or import client.ovpn file using the command line with Network Manager on a Ubuntu Linux or CentOS Linux desktop?
I installed an OpenVPN server with Pi-hole software to block block ads, reduced my 4G/3G/LTE traffic on the same Debian or Ubuntu Linux server. How do I upgrade my Pi-hole to the latest version using command line?
