Prefer a graphical setup? Add SlickVPN through the Network Manager GUI so you can connect from the system tray.
Run: sudo apt install network-manager-openvpn-gnome, then log out and back in so the option appears.
Open Settings → Network, click the + beside VPN, and choose “Import from file…”.
Select your SlickVPN .ovpn file. Network Manager fills in the gateway, certificates and cipher automatically.
Enter your VPN username and password, save, then toggle the VPN on from the network menu.
