1.安装poppler-data

apt-get install poppler-data

2.编辑/etc/fonts/conf.d/49-sansserif.conf 为

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<!--
If the font still has no generic name, add sans-serif
-->
<match target="pattern">
<test qual="all" name="family" compare="not_eq">
<string>sans-serif</string>
</test>
<test qual="all" name="family" compare="not_eq">
<string>serif</string>
</test>
<test qual="all" name="family" compare="not_eq">
<string>monospace</string>
</test>
<edit name="family" mode="append_last">
<!--    <string>sans-serif</string> -->
<string>宋体</string>
</edit>
</match>
</fontconfig>

修改红色部分为想用的字体

OK！
