Ubuntu 16.04下安装sogou 拼音输入法的错误问题

引言： sogou输入法是市场上最为好用和流行的输入法，最为良心的是还有Linux版本，这让我等Linux人士欢呼雀跃。在新出的Ubuntu 16.04上安装sogou输入法的时候，碰到了一些问题，主要还是依赖包没有正确安装，我们一起来看如何来解决这个问题。

1.  环境介绍

Ubuntu 16.04,   sogou输入法： sogoupinyin\_2.0.0.0078\_amd64

2.  问题表现

sudo dpkg -i sogoupinyin_2.0.0.0078_amd64.deb

错误信息如下：

sogoupinyin : Depends: libopencc2 but it is not installable or
    libopencc1 but it is not going to be installed
    Depends: fcitx-libs (>= 4.2.7) but it is not going to be installed
    Depends: fcitx-libs-qt (>= 4.2.7) but it is not going to be installed
    Recommends: fonts-droid-fallback but it is not going to be installed or
    fonts-droid but it is not installable
    E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

一看就知道是依赖包存在问题

3.  问题分析

之前在Ubuntu 15.10的版本之时，使用同样的sogou版本，不存在此类的问题。 但是在Ubuntu 16.04中，却存在此类问题，说明Ubuntu升级之后，sogou输入法并未做相应的系统兼容性测试， 故起最高的Ubuntu支持版本时15.10.

虽然我们知道了问题，但是该如何解决呢？

基于错误信息，我们发现起依赖包有以下几个： libopencc1 libopencc2,  fcitx-libs, fcitx-libs-qt  font-droid-fallback.

分析： 经过各种尝试，发现依然无法正常解决问题，类库包之间的依赖关系还是非常复杂的。

5. 问题解决

5.1 移除sogou输入法， 由于其安装不完整

sudo apt remove sogoupinyin

执行过程：

Reading package lists... Done
    Building dependency tree       
    Reading state information... Done
    The following packages will be REMOVED:
      sogoupinyin

5.2 正确的包安装姿势

sudo apt install libopencc1 fcitx-libs fcitx-libs-qt fonts-droid-fallback

5.3 重新安装sogou输入法

sudo dpkg -i sogoupinyin_2.0.0.0078_amd64.deb

结果 一切顺利，没有报类似的错误信息

6. 总结

安装依赖需要一次安装完成，切勿单个安装，主要是由于包之间彼此会有一定的依赖关系，这个是你无法准确定位的，故在 一次安装动作中做完。

另外， sogou输入法的Linux版本目前只兼容到Ubunut 15.10， 请大家彼此周知该情况。
