I think I am also affected. I get in xenial 64-bit for xfce and ubuntu- mate-core:
locale -a C C.UTF-8 POSIX en_AG en_AG.utf8 en_AU.utf8 en_BW.utf8 en_CA.utf8 en_GB.utf8 en_HK.utf8 en_IE.utf8 en_NZ.utf8 en_PH.utf8 en_SG.utf8 en_US.utf8 en_ZA.utf8 en_ZM en_ZM.utf8 en_ZW.utf8 Although I installed language-pack-gnome-pl language-pack-gnome-pl-base language-pack-pl language-pack-pl-base I set pl_PL with sudo dpkg-reconfigure locales and later also in Mate languages setting In Mausepad or Pluma and LibreOffice I do get Polish letters but Mate interface is still in English. In Mate language support Polish is not even listed (not visible as installed). I also have problems with typing in Polish in wine. I don't know if this is related but might be. https://bugs.launchpad.net/ubuntu/+source/wine1.6/+bug/1563961 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to language-pack-en-base in Ubuntu. https://bugs.launchpad.net/bugs/1562279 Title: Can't set en_NZ locale Status in language-pack-en-base package in Ubuntu: Confirmed Bug description: After updating language-pack-en and language-pack-en-base in Xubuntu 16.04, I can no longer set en_NZ.UTF-8 as my locale in lightdm- greeter. Current locale, after fiddling with language support, is: LANG=en_US.UTF-8 LANGUAGE=en LC_CTYPE="en_US.UTF-8" LC_NUMERIC=en_NZ.UTF-8 LC_TIME=en_NZ.UTF-8 LC_COLLATE="en_US.UTF-8" LC_MONETARY=en_NZ.UTF-8 LC_MESSAGES="en_US.UTF-8" LC_PAPER=en_NZ.UTF-8 LC_NAME=en_NZ.UTF-8 LC_ADDRESS=en_NZ.UTF-8 LC_TELEPHONE=en_NZ.UTF-8 LC_MEASUREMENT=en_NZ.UTF-8 LC_IDENTIFICATION=en_NZ.UTF-8 LC_ALL= Previously, everything was "en_NZ.UTF-8" I imagine that the same issue is going to apply to a number of English-language locales other than Australia, Canada, UK and US. These four, plus a generic "en" (which appears to default to en_US) are all that are displayed in the lightdm-greeter language menu.
