Configure the locale and keyboard layout in Raspbian

I have a keyboard with the spanish layout (with the “ñ” key, etc.) but Raspbian comes by default only with the english locale and keyboard layout. To make my keyboard work correctly I first added the spanish es_ES.UTF-8 locale on the system:

$ sudo dpkg-reconfigure locales

Then configure the keyboard layout:

$ sudo dpkg-reconfigure keyboard-configuration

You may also change the time zone to your country:

$ sudo dpkg-reconfigure tzdata
