Any idea? How to fix this problem. Out me every time startup or reboot ??
You should run
systemctl status console-setup.service as per suggestion to have a look at the problem.
You may need to execute
sudo dpkg-reconfigure keyboard-configuration
sudo dpkg-reconfigure console-setup
and provide suitable answers to the questions those commands ask to recreate a 'working' configuration.
As suggested here, you can try:
sudo systemctl restart console-setup.service
I had the same problem on Debian Stretch, and this resolved it for me. The error did not recur on reboot.
