Hi Joulinar,
thank you for taking care for PiVPN as well.
I had no problems to install and run Wireguard on this machine via the dietpi-software installer.
So this seems to be a PiVPN issue, rejecting my Kernel.
Just liked to use the GUI, but I’m fine with the basic solution too.
Thank you for clarification, Frans
you are lucky, because on upcoming version DietPi v 8.12, we will disable Wireguard for all systems where Wireguard kernel module is not available v8.12 · MichaIng/DietPi@e8a944a · GitHub
Means systems who require DKMS to build Wireguard are not supported anymore.
