使用 ltugboat 安装 guit 软件包时出错

Question

此 MWE

% arara: pdflatex
\documentclass[final]{ltugboat} 
\usepackage{guit}
\begin{document} 
    It worked a week ago 
    \GuITmeeting[style=inline,year=2019]!   
\end{document}

给出了这个错误

! No declaration for shape OT1/pzc/mb/it.
sub@sfcnt ...e forspace shapespace mandatory@arg }
                                                  error@fontshape else #1{Fo...
l.6     \GuITmeeting[style=inline,year=2019]
                                         !  
? 
! Emergency stop.

直到一周前它仍然有效。

如果有用的话，这就是我的日志的开始：
