Despite I've got today's version (2017-08-27), I cannot update to French the missing parts

(all the following is an approximate translation, because these parts are actually in French)
I go to: preferences > languages update
1st windows in response: languages not completely installed
2nd windows in response: impossible to install languages completely
3rd windows in response: you are not authorized to perform this action

if I click on details, I can read the following:
org.freedesktop.PolicyKit.Error.Failed: ('system-bus-name', {'name': ':1.86'}): org.debian.apt.install-or-remove-packages

So for example, Libre Office is in English instead of French
