环境是Ubuntu 16.04 .3 LTS，昨天刚申领到的云服务器。
按照官方步骤安装依赖库，基本很顺利的装完。在安装libboost-all-dev的时候遇到一个坑

```
libboost-all-dev : Depends: libboost-mpi-dev but it is not going to be installed
                    Depends: libboost-mpi-python-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
```
<br>apt不能解决依赖自己来：
```
apt-get install libboost-mpi-dev
```
<br>还是报错：
```
libboost-mpi-dev : Depends: libboost-mpi1.58-dev but it is not going to be installed
```
<br>然后：
```
apt-get install libboost-mpi1.58-dev
```
<br>报错：
```
libboost-mpi1.58-dev : Depends: mpi-default-dev but it is not going to be installed
```
.
.
.
此处省略300字 :-)
最终定位到：
```
libnuma-dev : Depends: libnuma1 (= 2.0.11-1ubuntu1) but 2.0.11-1ubuntu1.1 is to be installed
```
<br>就差了0.1至于这么为难我吗？心塞！


解决方法如下：
先删除libnuma1，再安装libnuma-dev
```
sudo apt-get remove libnuma1
sudo apt-get install libnuma-dev
```

## 总结：

Linux上面安装东西一定要发挥**打破沙锅问到底**的精神，一层层找，找到最后一层依赖不能安装的问题，然后移除，再安装。

*我把这个坑填了，遇到的朋友们踩着过吧，哈哈哈。。。*
