\section{Fast \& light console-based Music Player}
The project aims to build a fast, light, and high-quality music player that is console-based with a simple and easy-to-use GUI written on shell scripts made for Linux systems. The music player is being designed to be able to decode most modern audio file formats.
%------------------------------------------------
\subsection{Utility Requirements}
The utility requires very little computing power to function and is very efficient with CPU usage. For Linux OS, the utility has about 3\% to 4\% CPU usage on playing a high quality VBR MP3 on a Pentium 366MHz machine.\\
Requirements are listed as below:
\begin{itemize}
\item mpg123 - an MPEG player and decoder library
\item A Linux OS distribution
\item Atleast 100MHz of computing power
\end{itemize}
%------------------------------------------------
\subsection{Innovativeness \& Usefulness}
The music player is being developed with the goal of optimising CPU utilisation, while having an easy-to-use GUI to play high quality music.\\
Some proposed features of the utility are:
\begin{itemize} \itemsep 1pt
\item Support for various audio sub-systems
\item Simple but powerful control modes for frontend GUI
\item Support for playback through URL
\item Support for music playback from Cloud storage
\item Many audio data settings: resampling, choose channel, mono.
\item Support for Relative Volume Adjustment / Replay Gain
\end{itemize}
%------------------------------------------------
\subsection {Current status of development}
\begin{itemize} \itemsep -2pt
\item Basic functionality of the music player has been achieved.
\item Frontend user interface is under development and is being developed using Zenity/ncurses library.
\item Integration of proposed features into the GUI user interface of the utility has been started.
\end{itemize}

答案1
可能您有一个过时的 KOMA-Script 包，这就是您收到这些错误的原因。
除此之外，尽量避免fancyhdr与 KOMA 类一起使用，因为不推荐这样做。
scrlayer-scrpage您可以使用专门设计用于此类的包。
因此，你可以替换
\usepackage{fancyhdr} % Custom headers and footers
\pagestyle{fancyplain} % Makes all pages in the document conform to the custom headers and footers
\fancyhead{} % No page header - if you want one, create it in the same way as the footers below
\fancyfoot[L]{} % Empty left footer
\fancyfoot[C]{} % Empty center footer
\fancyfoot[R]{\thepage} % Page numbering for right footer
\renewcommand{\headrulewidth}{0pt} % Remove header underlines
\renewcommand{\footrulewidth}{0pt} % Remove footer underlines
只需
\usepackage{scrlayer-scrpage}
\clearpairofpagestyles
\ofoot[\pagemark]{\pagemark}
\pagestyle{scrheadings}
如果你有旧版本的 KOMA-Script，请替换
\usepackage{scrlayer-scrpage}
\clearpairofpagestyles
和
\usepackage{scrpage2}
\clearscrheadfoot
