一、環境介紹

   Ubuntu 16.04

   搜狗輸入法： sogoupinyin_2.0.0.0078_amd64

二、問題表現

sudo dpkg -i sogoupinyin_2.0.0.0078_amd64.deb 

錯誤信息如下：

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). 

一看就知道是依賴包存在問題

三、問題分析

之前在Ubuntu 15.10的版本之時，使用同樣的sogou版本，不存在此類的問題。 但是在Ubuntu 16.04中，卻存在此類問題，說明Ubuntu升級之后，sogou輸入法并未做相應的系統兼容性測試， 故起最高的Ubuntu支持版本時15.10.

雖然我們知道了問題，但是該如何解決呢？

基于錯誤信息，我們發現起依賴包有以下幾個： libopencc1 libopencc2,  fcitx-libs, fcitx-libs-qt  font-droid-fallback.
