Ubuntu 软件中心无法打开

当我尝试通过终端打开 Ubuntu 软件中心时显示以下内容：

$ software-center
2015-03-03 13:07:01,990 - softwarecenter.ui.gtk3.app - INFO - setting up proxy 'None'

    self.open(progress)

    self._list.read_main_list()
SystemError: E:Type ‘WEW’ is not known on line 3 in source list /etc/apt/sources.list.d/mono-xamarin.list

我记得我意外地输入了“WEW”，但我不确定如何改变这一点。

答案1

/etc/apt/sources.list.d/mono-xamarin.list第 3 行有一个格式错误的行。

最好的解决方案是使用编辑器打开该文件并查找第 3 行。然后您可以注释掉该行。只需#在该行的第一个字符中添加一个 - 字符即可。

然后再次运行software-center。
