$USERNAME is set by gdm3 in gdm-session-worker/gdm_session_worker_update_environment_from_passwd_info
along with $LOGNAME/$USER/$HOME/$SHELL. I imagine KDE has similar functionality so $USERNAME should suffice as a default non-root user in the event $SUDO_USER and $APT_LISTCHANGES_USER are not set. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
