我最近sudo apt-get update在 Ubuntu 14.04 中使用了该命令，现在当我想要安装软件包时，出现错误。
例如，当我sudo apt-get install vagrant用于安装 Vagrant 时，出现以下错误：
invoke-rc.d: initscript cups, action "start" failed.
dpkg: error processing package cups-daemon (--configure):
subprocess installed post-installation script returned error exit status 1
Setting up fontconfig (2.11.1-0ubuntu6) ...
