Linux/NetworkManager

Installing the VPN client

Note

The solution is based on openconnect package and therefore requires proper support for Global Protect protocol there in. Read Linux/Command Line to check if your Linux distribution is known to have problems with the Global Protect protocol implementation.

RHEL/Rocky/AlmaLinux/Fedora

Open a terminal and type there:

sudo dnf install epel-release
sudo dnf update epel-release
sudo dnf install NetworkManager-openconnect-gnome

Debian/Ubuntu

Open a terminal and type there:

sudo apt install network-manager-openconnect-gnome
