Second time the installed system have `ru` and `us` layouts, but the <Alt>+<Shift> is not defined.
The contents of keyboard configuration files is the following:
``` $ cat /etc/default/keyboard # KEYBOARD CONFIGURATION FILE
# Consult the keyboard(5) manual page.
XKBMODEL="pc105" XKBLAYOUT="us,ru" XKBVARIANT="," XKBOPTIONS="grp_led:scroll"
BACKSPACE="guess"
``` so keyboard layout switcher is not defined here.
There is something wrong with keyboard layout settings by installer.
