Hello, With Xubuntu Trusty 14.04.5 (Kernel 3.13.0.112), the LO version 4.4.7 is Ok. With LO Build ID: 1:5.2.5~rc1-0ubuntu1~trusty0 (french version) in Calc : Message "L'installation de polices sur demande n'est pas prise en charge. La détection automatique et l'installation des polices manquantes ne sont pas prises en charge actuellement." This, when i go to the window "Formatage des cellules". nota : LO 5.2.5 installed today with ppa:libreoffice/libreoffice-5-2 Thanks.

For information, an other PC with Xubuntu Xenial 16.04 (64 bits), and LO version 5.2.5 installed with the same ppa:libreoffice/libreoffice-5-2, Calc is Ok, no message.
