在我尝试安装 Skype 之后（为了做到这一点，我输入了一些我不记得是从这个论坛上得到的命令）我的软件中心在打开后立即关闭，我无法再通过终端安装任何软件包。
我还在菜单栏中收到此错误消息：
An error occurred. Please run package manager from the right-click menu or apt-get
in a terminal to see what is wrong. The error message was: Unknown error '<class<
'SystemError'>' (E:Malformed line 56 in source list (dist parse))'. This usually
means that your installed packages have unmet dependencies
这是我在终端中输入命令时得到的结果software-center：

我该怎么做才能解决这个问题？我拥有最新版本的 Ubuntu，但我还是一名新手。
答案1
只需暂时进入终端安装突触包管理器我的理解是它是软件中心的前身，基本上不太出故障
sudo apt-get install synaptic
安装完成后，打开它并进入软件中心>右键单击>重新安装或任何它说的
也可以尝试通过那里重新安装 skype - 它应该会告诉你（与软件中心不同），Skype 顺利运行还需要哪些其他软件
就这一点而言，你不能只安装 Linux 的二进制文件吗？这里？
