Question: I have a small application that uses playwright to scrape data from various websites. The application is Dockerized well and everything worked perfectly until I tried to re-build the Docker image (nothing really changed in the code) and it failed to install the playwright deps (like it used to before). This is the Dockerfile: FROM python:3.9-slim COPY ../../requirements/dev.txt ./ RUN python3 -m ensurepip RUN pip install -r dev.txt RUN playwright install RUN playwright install-deps ENV PYTHONPATH "${PYTHONPATH}:/app/" WORKDIR /code/src EXPOSE 8000 COPY ./src /app CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "8000", "--reload"]  This is the requirements: fastapi>=0.85.0 uvicorn>=0.18.3 bs4==0.0.1 playwright  This is the error message:  => ERROR [6/8] RUN playwright install-deps 4.1s ------ > [6/8] RUN playwright install-deps: #10 0.762 BEWARE: your OS is not officially supported by Playwright; installing dependencies for Ubuntu as a fallback. #10 0.762 Installing dependencies... #10 1.084 Get:1 http://deb.debian.org/debian bookworm InRelease [147 kB] #10 1.269 Get:2 http://deb.debian.org/debian bookworm-updates InRelease [52.1 kB] #10 1.338 Get:3 http://deb.debian.org/debian-security bookworm-security InRelease [48.0 kB] #10 1.407 Get:4 http://deb.debian.org/debian bookworm/main amd64 Packages [8904 kB] #10 2.278 Get:5 http://deb.debian.org/debian-security bookworm-security/main amd64 Packages [24.2 kB] #10 3.063 Fetched 9176 kB in 2s (4021 kB/s) #10 3.063 Reading package lists... #10 3.474 Reading package lists... #10 3.868 Building dependency tree... #10 3.969 Reading state information... #10 3.972 Package ttf-ubuntu-font-family is not available, but is referred to by another package. #10 3.972 This may mean that the package is missing, has been obsoleted, or #10 3.972 is only available from another source #10 3.972 #10 3.972 Package libjpeg-turbo8 is not available, but is referred to by another package. #10 3.972 This may mean that the package is missing, has been obsoleted, or #10 3.972 is only available from another source #10 3.972 #10 3.972 Package ttf-unifont is not available, but is referred to by another package. #10 3.972 This may mean that the package is missing, has been obsoleted, or #10 3.972 is only available from another source #10 3.972 However the following packages replace it: #10 3.972 fonts-unifont #10 3.972 #10 3.972 Package xfonts-cyrillic is not available, but is referred to by another package. #10 3.972 This may mean that the package is missing, has been obsoleted, or #10 3.972 is only available from another source #10 3.972 #10 3.974 E: Package 'ttf-unifont' has no installation candidate #10 3.974 E: Package 'xfonts-cyrillic' has no installation candidate #10 3.974 E: Package 'ttf-ubuntu-font-family' has no installation candidate #10 3.974 E: Unable to locate package libx264-155 #10 3.974 E: Unable to locate package libenchant1c2a #10 3.974 E: Unable to locate package libicu66 #10 3.974 E: Package 'libjpeg-turbo8' has no installation candidate #10 3.974 E: Unable to locate package libvpx6 #10 3.974 E: Unable to locate package libwebp6 #10 3.975 Failed to install browser dependencies #10 3.975 Error: Installation process exited with code: 100 ------ executor failed running [/bin/sh -c playwright install-deps]: exit code: 1  The command I'm running is 'docker-compose build'. Hope someone could help, Thanks.

Answer: Solution: I changed the base image to a newer version and now it is working properly. FROM python:3.10.7 instead of: FROM python:3.9-slim
