我尝试在 UBuntu 14.04 上安装 git-lfs。出现了一些错误，一些步骤是我随机执行的，我不记得确切的步骤顺序，但我卡在这里。
无论我尝试安装任何软件包，都会出现以下错误 -

我尝试通过执行 apt-get purge git-lfs 、 apt-get autoclean 来删除 git-lfs，但似乎没有任何帮助。
请告诉我如何修复 dpkg。我不再需要 git-lfs，所以我可以将其完全删除。
尝试了包裹系统坏了。该如何修复？。

apt-get clean 和 apt-get update 可以工作，但 apt-get install -f 会失败。而且我之前没有安装过 synaptic，所以现在无法安装任何新软件包。
