I am unable to compile a quiz document specifically only on linux machines. My code looks like:

%% Language and font encodings

usepackage[english]{babel}

usepackage[utf8x]{inputenc}

usepackage[T1]{fontenc}



%% Sets page size and margins

usepackage[a4paper,margin=1cm]{geometry}



%% Useful packages

usepackage{amsmath}

usepackage{graphicx}

usepackage{paralist}

setlengthFrameSep{4pt}





begin{document}

vspace{5mm}

begin{center}

fbox{fbox{parbox{2in}{centering

Quiz 1}}}



vspace{5mm}



makebox[textwidth]{Name:enspacehrulefill}

vspace{5mm}

makebox[textwidth]{Section:enspacehrulefill}

%questions being here



begin{questions}

    question[2]{Sample Question}

    begin{framed}

        begin{compactenum}[a.]

        item option 1.

        item Option 2.

        item option 3.

        item none of the above.

        end{compactenum}

end{framed}

end{questions}

end{center}

end{document} 

This code is compiling on mac systems as well as online services like overleaf, but fails on linux systems. The error file looks like
