我无意中（鲁莽地）删除了rm -rf我的/usr/share/fonts/truetype目录。我所有的 TrueType 字体现在都消失了。:/ 有什么办法可以找回它们吗？我在 Ubuntu 16.04 上。
答案1
只是经历了这个与另一个用户一起访问不同的目录。您可以查看哪些包在目录中有文件。就我而言：
$ dpkg -S /usr/share/fonts/truetype | cut -sd: -f1 | tr -d , | fold -w80
fonts-opensymbol ttf-mscorefonts-installer ttf-ubuntu-font-family fonts-symbola
fonts-liberation fonts-freefont-ttf fonts-droid-fallback fonts-dejavu-core
我们可以将其完善为一个命令，只需重新安装所有这些包：
sudo apt install --reinstall $(dpkg -S /usr/share/fonts/truetype | cut -sd: -f1 | tr -d ,)
这样做的好处是你可以根据你的包。

我生成了包含每个目录的软件包的列表我的 /usr/share/fonts/truetype。（我没有删除我的字体）。重新安装（使用sudo apt-get install --reinstall <package> <...>：
