Hebrew keyboard does not work

[Victor Porton]

When I switch the keyboard to Hebrew, it types English. (Russian input works, however.)

Maybe it was broken after running these Bash commands:

v="[('xkb', 'us'), ('xkb', 'ru+typewriter'), ('xkb', 'il')]"
gsettings set org.gnome.desktop.input-sources sources "$v"

Removing Hebrew layout "manually" (that is through the Gnome configuration, not through a script) and adding it back (manually too) does not help against the bug.

So, I can't type Hebrew anymore. Help!
