    You could use apt-get install to fix up missing dependencies. Example:

    FROM python:3.8.5
RUN apt-get update
RUN apt-get install --no-install-recommends -y 
 apt-utils ghostscript fontforge cabextract 
 wget
ARG WKHTML2PDF_VERSION='0.12.6-1'
RUN export VERSION_CODENAME=$(. /etc/os-release; echo $VERSION_CODENAME) 
 && wget https://github.com/wkhtmltopdf/packaging/releases/download/${WKHTML2PDF_VERSION}/wkhtmltox_${WKHTML2PDF_VERSION}.${VERSION_CODENAME}_amd64.deb -O wkhtmltox.deb
RUN dpkg -i wkhtmltox.deb || apt-get install -f -y

    I see a couple of problems here. First, you are trying to install an Ubuntu Bionic Beaver version of WKHTMLTOPDF on a Debian Buster os. So, I would recommend using the correct release.

    Second, you are clearly missing some dependencies as stated in the error message. So you should install those.

    Lastly, this is purely optional, but I would recommend grouping your install commands in one layer (one Docker command here RUN), this will help make your final image smaller.

    Here is the content of a Dockerfile that would build.

    FROM python:3.8.5

RUN set -e; 
    apt-get update; 
    apt-get install -y --no-install-recommends 
        apt-utils 
        ghostscript 
        fontforge 
        cabextract 
        wget 
        libjpeg62-turbo 
        xfonts-75dpi 
        xfonts-base; 
    wget https://gist.github.com/maxwelleite/10774746/raw/ttf-vista-fonts-installer.sh -q -O - | bash; 
    wget https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.buster_amd64.deb ; 
    dpkg -i wkhtmltox_0.12.6-1.buster_amd64.deb; 
    rm -rf rm -rf /var/lib/apt/lists/*

    Cheers
