NetworkManager nm-applet for initiating OpenVPN client connections on a Proxmox workstation?

[Colin 't Hart]

I use Proxmox as an XFCE-based workstation, following these instructions: https://pve.proxmox.com/wiki/Developer_Workstations_with_Proxmox_VE_and_X11

I need to be able to connect to an OpenVPN server with TOTP or Yubikey authentication so I'd like to be able to use the GUI to connect.
I installed the following packages:

• network-manager
• network-manager-gnome
• network-manager-openvpn
• network-manager-openvpn-gnome
• openvpn

nm-applet starts on login, and I'm able to create an OpenVPN configuration.

However, when I want to activate the connection, the configuration is greyed out and can't be clicked.

I have had this working previously (I think it was on Proxmox 6.x) , just not on this new install (8.2).

Anyone any ideas how I can get this to work?

Solved it. All I needed to do was to change

managed=false

to

managed=true

under [ifupdown] in /etc/NetworkManager/NetworkManager.conf
