一.首先到官网下载搜狗拼音输入法
sogou 拼音输入法
http://pinyin.sogou.com/linux/?r=pinyin
当前下载的版本是sogoupinyin_2.1.0.0086_amd64.deb
二.安装
如果直接使用dpki安装会报错，具体如下：
$ sudo dpkg –i sogoupinyin_2.0.0.0078_amd64.deb
报如下错：

这是缺少一些依赖包，使用如下命令安装依赖：
sudo apt install libopencc1 fcitx-libs fcitx-libs-qt
或者我使用了：
sudo apt-get install -f
来解决依赖包问题
然后再次安装：
$ sudo dpkg –i sogoupinyin_2.0.0.0078_amd64.deb

总结一下安装步骤，两步即可
sudo apt install libopencc1 fcitx-libs fcitx-libs-qt
sudo dpkg –i sogoupinyin_2.0.0.0078_amd64.deb
三.最重要的！：
选择输入法：
1.在Language Support中增加汉语，然后选择输入法系统为fcitx
2.重启系统
3.在Text Entry中增加Sogou Pinyin
4.使用Ctrl+space即可开启搜狗输入法
