Cant change from develop to stable

Hi I have installed Probebasic, each time i open it, i get the message about being in develop mode, when i go to change the repos to the stable mode, it is already down as stable mode!

I have tried to update Probe basic and get the following error.

Building module:

many thanks

the dkms drivers require linux-headers for your kernel version. I don't think its installed.
The dkms system compiles the driver for kernels if they are changed or upgraded and the headers are required
