That Dockerfile doesn't have a `CMD`; how do you run it? It seems like you're missing a couple of runtime C shared libraries too, what have you tried to install those? — David Maze, Apr 13 '20 at 14:04

I solved by adding the next lines to my Debian Buster image based dockerfile (wkhtmlto* version 0.12.6-1, June 2021)

RUN apt-get update -qq && apt-get install -y \
    # packages required by wkhtmlto*:
    xfonts-base \
    xfonts-75dpi \
    pdftk # -> only if needed... \
    # ...other custom packages...

RUN curl -L#o wkhtmltopdf.deb https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.buster_amd64.deb
RUN dpkg -i wkhtmltopdf.deb; apt-get install -y -f

# Remember to clean your package manager cache to reduce your custom image size...
RUN apt-get clean all \
    && rm -rvf /var/lib/apt/lists/*

You can find other builds of the same package here: https://github.com/wkhtmltopdf/packaging/releases/0.12.6-1
