# lualatex and polyglossia with \setdefaultlanguage{german} does not work after recent texlive update [closed]

Here is a minimal example:

\documentclass{article}
\usepackage{polyglossia}
\setdefaultlanguage{german}

\begin{document}
Hallo Welt!
\end{document}


And here is the error message:

(/mnt/software/texlive/2015/texmf-dist/tex/luatex/ctablestack/ctablestack.sty)))

Setting \setdefaultlanguage{english} works well.

Thanks Georg

Update: The minimal example above works well if german is replaced by ngerman. Nevertheless, adding the line \usepackage{biblatex} again produces an error. Here is a minimal example:

\documentclass{article}

\usepackage{polyglossia}\setdefaultlanguage{ngerman}
\usepackage{biblatex}

\begin{document}
Hallo Welt!
\end{document}


Here is the error message:

(/mnt/software/texlive/2015/texmf-dist/tex/latex/biblatex/biblatex.cfg)))

Package biblatex Warning: Upgrade package 'polyglossia' to >v1.42.0 recommended.

• using ngerman instead of german avoids the error but doesn't solve the underlying problem. I suggest to use \usepackage[ngerman]{babel} until polyglossia and/or babel is updated (or go back to the previous babel). – Ulrike Fischer Feb 6 '16 at 22:46
• I'm still waiting for a polyglossia update ... I raised a ticket there a while ago. – PLK May 29 '16 at 20:36
• As of today (October 1, 2016) neither example raises errors, provided in the second one the language call is according to polyglossia rules, that is, german and not ngerman`. – egreg Oct 1 '16 at 22:15
• I'm voting to close this question as off-topic because the problem can not be reproduced any more. It was due to several bugs in several packages, and the actual problem shifted over time. – moewe May 28 '17 at 13:36
