我的apt-get无法使用。一直显示malformed line 63。此外，每次我尝试下载 Chrome 时，它都显示“软件索引已损坏”。
我不知道自己在做什么。Chrome 崩溃后，我设法卸载了它，但现在 Firefox 不允许我查看我的 Gmail 或发送任何消息。我无法重新安装 Chrome。
这一切都始于我尝试安装 Adobe Reader 时，我终于明白了，它甚至不能正常工作。我的打印机也不能 - 我不知道如何扫描任何东西，也无法下载简单的扫描或弄清楚。
当我尝试访问 Ubuntu 软件中心时，它关闭了。我无法用这个操作系统做任何事情，这太令人沮丧了。我甚至无法从 14.04 升级。我该怎么办？

真是一团糟...
我已经编辑了您原始的 sources.list 文件，它应该看起来更像这样......
/etc/apt/sources.list.d/*.list... 中可能还存在其他错误，对于这些错误，您需要查看每个单独的错误，然后搜索 *.list 文件并进行更正。（例如：getdeb 不再存在，因此您可以删除该特定的 .list 文件)...
