我真的不知道发生了什么，重启后我收到很多崩溃消息，如果我打开 Firefox 或 Synaptic，它们会崩溃。Synaptic 返回这个：
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_raring-security_main_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.
然后顶部面板上出现崩溃图标，并且有一些关于mergelist的错误。我用谷歌搜索，发现这个没用sudo rm /var/lib/apt/lists/* -vf sudo apt-get update。为了能够在浏览器中工作，我删除了/var/lib/apt/lists. 如果我尝试sudo apt-get update，我会得到这个：
