Erst mal das Minimalbeispiel:
\documentclass[12pt,paper=a4,fleqn]{scrartcl} % \usepackage{cloze} % \begin{document} Jemand musste Josef K. \cloze{verleumdet} haben. \end{document}
Die Fehlermeldungen:
! Class scrartcl Error: undefined old font command `\it'.
You should note that since 1994 LaTeX2e provides a new font selection scheme called NFSS2 with several new, combinable font commands. KOMA-Script classes had defined the old font commands like `\it' only for compatibility with old LaTeX 2.09 document styles of Script 2.0. Nevertheless, these commands are deprecated and undocumented at least since 2003. Since 2013 KOMA-Script classes warned about soon removement of these deprecated commands. Now, after two decades of LaTeX2e and NFSS2, these commands will not work any more. If loading a package results in this error message, you should contact the author of that package and ask him to replace the deprecated font command `\it', e.g., by `\normalfont \itshape `. Otherwise you should reconfigure or replace the package. If you have used the old font command `\it' yourself, you should replace it, e.g., by `\normalfont \itshape '. To make it work for now, you can use the already also deprecated class option `enabledeprecatedfontcommands'.
Ist "enabledeprecatedfontcommands"
\documentclass[12pt,paper=a4,fleqn,enabledeprecatedfontcommands]{scrartcl}
auf Dauer ein echtes Problem?
Wenn ich das Paket lokal selber anpassen möchte, wo muss ich da suchen? Also "\it" mit "normalfont \itshape" ersetzen. Hab Ubuntu 20.04 und Vanilla TeX Live 2020. Unter /usr/local/texlive/2020 oder ~/.texlive2020?
PS: Ich werde das auch bei Gelegenheit mal bei github posten ...
