Unfortunately I don’t know when v150 will be available.
The fact that you are the only one experiencing this problem leads me to believe that it most probably is an issue with your installation rather than a bug in DietPi itself, but as I said before I am not qualified to dig any deeper.
Let’s wait for help from the other moderators.
EDIT: I have just read this.
Have you by any chance forced the update of the kernel?
