# Hyphenation not working anymore - polyglossia

So I am switching from Windows to Ubuntu. I have finally managed to compile the text in Linux (with texstudio - LuaLaTex), only one thing is amiss: nothing is hyphenated anymore. In windows it works as it should, but in Linux it does not. It now looks like this:

Here's my MWE:

\documentclass[a4paper,11pt,oneside]{report}

\usepackage{fontspec}
\usepackage[final]{microtype}
\defaultfontfeatures{Ligatures=TeX, Scale=MatchLowercase}
\usepackage{polyglossia}
\setmainlanguage[spelling=new,babelshorthands=true]{german}

• Did you install the language package of TeXLive? It's package texlive-lang-european – user2478 Jan 7 '18 at 17:21
• I installed it now (via apt-get, tlmgr install does not work, it says package not present in repository) - Still doesn't work. – Viktor Gruber Jan 7 '18 at 17:28
• It is in general not a good idea using the TeXLive from Ubuntu. Installing the Distribution from TUG.org makes more sense: github.com/scottkosty/install-tl-ubuntu works also for TL2017 – user2478 Jan 7 '18 at 18:34
