PDF font issue in Linux - Accepting truefont EULA?

GemBox.Pdf
1

Hi. I am printing some PDFs inside docker.
Things worked well till 2 months ago. Application code and Gembox version not changed since then. Suddenly we have font issue.

I am suspecting this line cause an issue in the docker file

RUN apt-get update && apt-get install -y libfreetype6 libfontconfig1 libc6-dev ttf-mscorefonts-installer fontconfig

ttf-mscorefonts-installer seems to complain about EULA must be accepted. On my local everything is building fine and no EULA confirmation menu pops up but on the build server it seems confirmation is needed

Do anyone face the same issue?

Can you send us a small Visual Studio project that reproduces your issue?
Or perhaps just a Dockerfile will be enough?
I’ll try to reproduce the issue and investigate it.

In the Dockerfile there is only that notable line

RUN apt-get update && apt-get install -y libfreetype6 libfontconfig1 libc6-dev ttf-mscorefonts-installer fontconfig

I have a part of the build log

Do you reproduce the same issue with our Docker example project?

I’m afraid I was unable to reproduce your problem.
Nevertheless, try using this:

RUN apt-get update \
    && apt-get install -y --allow-unauthenticated \
    libfreetype6 libfontconfig1 libc6-dev \
    fontconfig \
    ttf-mscorefonts-installer

I hope it helps.
