Hello, how to install L2tp vpn? Sorry for my bad english.
Clear Linux has
wireguard support and
openvpn packages. These may or may not work easily with
NetworkManager - you’ll have to try it.
I personally am a big fan of
wireguard since it can work with just a simple text config file set and only needs
systemd-networkd, but, it’s probably a little spartan for people.
