I have a problem when I build lumen on docker, but when the build process is finished there is an error like this :
E: Package 'libpng12-dev' has no installation candidate ERROR: Service 'app' failed to build: The command '/bin/sh -c apt-get update && apt-get install -y libpng12-dev libjpeg-dev libpq-dev && rm -rf /var/lib/apt/lists/* && docker-php-ext-configure gd --with-png- dir=/usr --with-jpeg-dir=/usr && docker-php-ext-install gd mbstring pdo pdo_mysql pdo_pgsql zip' returned a non-zero code: 100
So the build process fails. Has anyone ever had a case like me? I hope someone can provide a solution.
