After updating of system keyboard is broken! I can not add keyboard layout! Button "Add" is disabled!

How I can restore the system?

See here

$ cat /etc/default/keyboard 
# KEYBOARD CONFIGURATION FILE 
# Consult the keyboard(5) manual page. 
XKBMODEL="pc105" 
XKBLAYOUT="us" 
XKBVARIANT="" 
XKBOPTIONS="" 
BACKSPACE="guess"

$ apt-cache policy mate-control-center
mate-control-center: 
  Installed: 1.20.2-2ubuntu1
  Candidate: 1.20.2-2ubuntu1 
  Version table: 
 *** 1.20.2-2ubuntu1 500 
        500 http://ru.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages
        100 /var/lib/dpkg/status

  • What is your Ubuntu version? What is your MATE version? What do you mean by "After updating of system keyboard "? Please add output of `cat /etc/default/keyboard` and `apt-cache policy mate-control-center` to the question by [editing it](https://askubuntu.com/posts/1198865/edit). – N0rbert Dec 27 '19 at 20:11
  • Also please add output of `gsettings list-recursively org.mate.peripherals-keyboard-xkb.kbd` to the question. – N0rbert Dec 27 '19 at 20:19
  • `$ cat /etc/default/keyboard # KEYBOARD CONFIGURATION FILE # Consult the keyboard(5) manual page. XKBMODEL="pc105" XKBLAYOUT="us" XKBVARIANT="" XKBOPTIONS="" BACKSPACE="guess"` – Сергей Новиков Dec 29 '19 at 07:43

You have to change /etc/default/keyboard to correct values with single long command below:

cat <<EOF | sudo tee /etc/default/keyboard 
# KEYBOARD CONFIGURATION FILE 
# Consult the keyboard(5) manual page. 
XKBMODEL="pc105"
XKBLAYOUT="us,ru"
XKBVARIANT=","
XKBOPTIONS="grp:alt_shift_toggle"
BACKSPACE="guess"

EOF

and then run sudo dpkg-reconfigure keyboard-configuration
and then you can set keyboard layouts from Keyboard Preferences (mate-keyboard-properties) .
