一、环境介绍
Ubuntu 16.04
搜狗输入法： sogoupinyin_2.0.0.0078_amd64
二、问题表现
|
1
|
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
三、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。
五、问题解决

5.2 正确的包安装姿势
|
1
|
sudo apt install libopencc1 fcitx-libs fcitx-libs-qt fonts-droid-fallback |
5.3 重新安装sogou输入法
|
1
|
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
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。
另外需要注意的是： 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。
