Hi @jasonyunliang, Yeah, this is a known issue and is already open in #148 and #719. Hence I'm going to close this off as a duplicate. Also referenced in #2182 and #1964.

I have previously suggested using our wkhtmltopdf option as a workaround, but this has security implications and may not be available in your docker environment.

Hi @ssddanbrown, I cannot found /usr/bin/wkhtmltopdf in linuxserver/bookstack docker image(TAG 23.06.2), has it been removed from the docker image? Do you have plan to support it again in subsequent versions?

Hi, wkhtmltopdf is removed from the official image, you need to make a new docker image that contains wkhtmltopdf. My Dockerfile is below for your reference, please note: I also install SimSun.ttf that supports chinese font, make sure SimSun.ttf existence if you use the following Dockerfile.

FROM surnet/alpine-wkhtmltopdf:3.16.2-0.12.6-full as wkhtmltopdf

COPY SimSun.ttf /usr/share/fonts/SimSun.ttf

FROM lscr.io/linuxserver/bookstack

RUN echo -e http://mirrors.ustc.edu.cn/alpine/v3.7/main/ > /etc/apk/repositories
RUN echo -e https://mirrors.aliyun.com/alpine/v3.17/community >> /etc/apk/repositories
#RUN echo -e http://dl-cdn.alpinelinux.org/alpine/v3.7/community >> /etc/apk/repositories

# Install dependencies for wkhtmltopdf
RUN apk add --no-cache \
     libxrender \
     openssl1.1-compat \

     ttf-dejavu \

     ttf-freefont \
     ttf-liberation \
  && mkfontscale && mkfontdir && fc-cache -f

# RUN mkdir -p /usr/share/fonts/win
COPY --from=wkhtmltopdf /usr/share/fonts/SimSun.ttf /usr/share/fonts/SimSun.ttf

# Copy wkhtmltopdf files from docker-wkhtmltopdf image
COPY --from=wkhtmltopdf /bin/wkhtmltopdf /bin/wkhtmltopdf
