По-видимому, потому что:

Кажется правильным библиотека установлена, но для CPT требуется более старая версия - 52 вместо 55. Пакет Debian, содержащий более старую версию libicui18n, доступен по адресу http://security.ubuntu.com/ubuntu/pool/main/i/icu. /libicu52_52.1-3ubuntu0.8_amd64.deb.

вручную установите старый пакет:

thufir@dur:~/deb$
