[積丹尼 Dan Jacobson <jidanni@jidanni.org>]

OK, I have captured both:

$ pstree -al

During the first occasion:

             `-aptitude safe-upgrade
                  |-sh -c /usr/sbin/dpkg-preconfigure --apt || true
                  |   `-dpkg-preconfigu -w /usr/sbin/dpkg-preconfigure --apt
                  |       |-(dpkg-preconfigu)
                  |       |-keyboard-config /tmp/keyboard-configuration.config.BvbEEk configure 1.150
                  |       `-whiptail --backtitle Package configuration
             --title Configuring keyboard-configuration --output-fd 12
             --default-item Generic 105-key (Intl) PC --menu Please
             select the model of the keyboard of this
             machine.\012\012Keyboard m

During the second occasion:

              `-aptitude safe-upgrade
                  |-dpkg --status-fd 38 --no-triggers --configure --pending
                  |   `-frontend -w /usr/share/debconf/frontend /var/lib/dpkg/info/keyboard-configuration.postinst configure 1.150
                  |       |-keyboard-config /var/lib/dpkg/info/keyboard-configuration.config configure 1.150
                  |       `-whiptail --backtitle Package configuration
              --title Configuring keyboard-configuration --output-fd 11
              --default-item Generic 105-key (Intl) PC --menu Please
              select the model of the keyboard of this machine.\012\01

They only happen a few minutes apart, during upgrade.
