一、环境介绍
Ubuntu 16.04
搜狗输入法： sogoupinyin_2.0.0.0078_amd64
二、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
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.
