The following packages have been kept back [Solved]

1、问题描述

OS: kali

自上一次执行

sudo apt-get upgrade

之后，系统任务栏中一直有待升级提醒，而再执行

sudo apt-get upgrade

却是如下提示

Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages have been kept back:
  mitmproxy python-netlib python-openssl
0 upgraded, 0 newly installed, 0 to remove and 3 not upgraded.

任务栏右上角图示：

2、解决方法

$ sudo apt-get -u dist-upgrade

3、析

有部份packages的安装版比release版新而出现”The following packages have been kept back”这个问题，使用2中的解决方法 统一更新到发布的版本。

这条命令会强制更新软件包到最新版本，并自动解决缺少的依赖包。
