请帮帮忙。我已经尝试安装skype很长一段时间了，我尝试过无数次的修复。

更新:我也不能安装蒸汽，因为这一点。

Answer 1

有时我也会遇到同样的问题。我想你不能安装任何东西，对吗？我用两个解决方案解决了这个问题。

首先，尝试更好的镜像更新。

从图形模式中找到最快的镜像非常容易。您要做的就是打开，转到Settings ->存储库。从Ubuntu软件部分，在“从”下拉框中选择“其他”，然后单击。

第二，移除任何不能工作的ppa。

使用GUI删除PPA :还可以通过打开软件源(> Edit > Software )删除PPA，然后转到“其他软件”选项卡，选择要删除的PPA，然后单击" remove“按钮。每个PPA在这里应该有两行，一行用于编译包，一行用于源，因此移除这两行。

其中一个可能对你有帮助。
