DarkMark GUI Missing Text in Docker Container

[lost-robot]

Awesome work!!! ...I have been able to use DarkHelp within a Docker container without any issues. When I launch DarkMark from a running container there is no text in the GUI. Any idea regarding what the cause could be? Thanks!

Here is the Dockerfile:

# FROM nvidia/cuda:11.7.1-cudnn8-devel-ubuntu18.04

Here is the run script:

#! /bin/bash

xhost +si:localuser:root # allow containers to communicate with X server

docker run --rm -it --privileged \
       --env DISPLAY=$DISPLAY \
       --env=LOCAL_USER_ID="$(id -u)" \
       -v /tmp/.X11-unix:/tmp/.X11-unix \
       --gpus all \
       --name=darkmark_container darkmark:latest \

Here is the build script:

#! /bin/bash

docker build -t darkmark --build-arg USER_ID=$(id -u) --build-arg GROUP_ID=$(id -g) .

Start DarkMark command from within the container:

/usr/bin/DarkMark

Yes, I'm guessing you don't have the necessary fonts installed.

See issue #21 and issue #23.

[lost-robot]

Yes, that was indeed the issue. Thanks very much!

...'sudo apt install fonts-liberation' fixed the problem.
