安装救生员RSS阅读器时出错

Question

一旦我按下安装，我得到：

Package dependencies cannot be resolved
This error could be caused by required additional software packages which are missing or not installable. Furthermore there could be a conflict between software packages which are not allowed to be installed at the same time.

Details
The following packages have unmet dependencies:

Answer 1

据我所见，这是包系统中的一个临时故障--所以现在应该没事了。

更新计算机(如本问题：如何更新Ubuntu？中所概述的)，然后再试一次。

Answer 2

如果遇到此类问题，首先要运行这两个命令

sudo apt-get update

紧接着是

sudo apt-获得升级

我有时也跑

sudo apt-获取dist-升级

然后试着安装
