Ok. Seems i find my problem. I didnt had installed the apop flightmode before the flightmode-toggle.
But here is the problem. Now it doesnt let mi install from the store (conflict with other paket).
with apt-get have the notice that its depend from system-ui (i've had replaced with unrestricted-system-ui).
Now i have problems to install other packages also to remove apps. What can i do?
