使用 apt-get 安装软件包时出现 CUPS 错误

Question

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) ...

我搜索了有关此错误的详细信息，有人建议使用sudo apt-get upgrade. 我试过这个，但它没有帮助。

我该如何解决这个问题？

Answer 1

这意味着您添加了错误的 source.list 并且您的库因此而损坏。就我而言，我在 ubuntu 14.04 中添加了 13.04 的源列表，以便根据 askubuntu.com 中某个人的回答使某些功能正常工作，这是我做的最愚蠢的事情，并且学会了永远不要添加旧版本的库。但它确实解决了问题，并且一切正常，直到我重新启动系统。

当我遇到这个错误时，我通过ubuntu重新启动，但无法再次启动。重新启动失败。所以我拿了一个随身碟并将 14.04 升级到 16.04，一切都修复了，我也能够安装这个杯子的东西。这是我唯一能做的事。

所以使用：

sudo apt-get upgrade
