debian安装字体
-
在/usr/share/fonts/truetype/下建立文件夹myfonts，然后拷贝上述字体到改文件夹下。
sudo mkdir /usr/share/fonts/truetype/myfonts cp *.ttf /usr/share/fonts/truetype/myfonts/ -
更改myfonts和该目录下面的权限，可以都设成777
sudo chmod -c 777 /usr/share/fonts/truetype/myfonts sudo chmode -c 777 /usr/share/fonts/truetype/myfonts/* 最后就是注册新添加字体了，执行如下命令
sudo mkfontscale
sudo mkfontdir
sudo fc-cache -fv
