Fontconfig warning: & ldquo; /etc/fonts/conf.d/90-fonts-unfonts-core.conf”

Я часто получаю следующую ошибку. (Пример: при запуске zenity, firefox и т. Д. Команд / приложений.)

Fontconfig warning: "/etc/fonts/conf.d/90-fonts-unfonts-core.conf", line 11: Having multiple values in <test> isn't supported and may not work as expected

Вот содержимое файла /etc/fonts/conf.d/90-fonts-unfonts-core.conf:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">

        <edit name="hintstyle" mode="assign" binding="strong"><const>hintslight</const></edit>
    </match>
</fontconfig>

Как сделать решить это?
