无法在 Ubuntu 16.04 中安装 g++ 编译器

首先我像这样更新，sudo apt-get update 最后显示如下：

Fetched 323 kB in 1s (247 kB/s)                                     
Reading package lists... Done

然后我安装 g++ 编译器。显示如下：

bharat@bharat-OptiPlex-3050:~$ sudo apt-get install g++
Reading package lists... Done
Building dependency tree       
Reading state information... Done
g++ is already the newest version (4:5.3.1-1ubuntu1).
The following packages were automatically installed and are no longer required:
  canonical-poke libappindicator1 libbonobo2-0 libbonobo2-common libgnome-2-0
  libgnome2-common libgnomevfs2-0 libgnomevfs2-common liborbit-2-0
  linux-headers-4.4.0-23 linux-headers-4.4.0-23-generic
  linux-image-4.4.0-23-generic linux-image-extra-4.4.0-23-generic
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

我需要解决方案，请帮助我。
