Ubuntu 16.04 installation sogou Pinyin Input Method error problem resolution _linux

First, the environment introduction

Ubuntu 16.04

Sogou Input Method: Sogoupinyin_2.0.0.0078_amd64

Ii. performance of the problem

The error message is as follows:

SOGOUPINYIN:DEPENDS:LIBOPENCC2 But it is isn't installable or 
libopencc1 but it is isn't going to be installed 
Depe Nds:fcitx-libs (>= 4.2.7) But it is isn't going to being installed 
DEPENDS:FCITX-LIBS-QT (>= 4.2.7) but it is not g Oing to being installed 
Recommends:fonts-droid-fallback But it is isn't going to be installed or 
fonts-droid but it i s not installable 

I know it's a problem with a dependency pack.

Third, the problem analysis

Previous versions of Ubuntu 15.10, using the same Sogou version, do not have this type of problem. However, in Ubuntu 16.04, there is such a problem, that after the Ubuntu upgrade, Sogou IME did not do the corresponding system compatibility test, so the highest Ubuntu support version of 15.10.

Although we know the problem, but how to solve it?

Based on the error message, we found that the dependency pack has the following: Libopencc1 Libopencc2, Fcitx-libs, FCITX-LIBS-QT font-droid-fallback.

Analysis: after a variety of attempts to find that the problem still does not work correctly, the dependencies between class library packages are very complex.

V. Problem-solving

5.1 Remove Sogou Input method, because its installation is incomplete

5.2 Correct package mounting posture

5.3 Reinstall Sogou IME

sudo dpkg-i sogoupinyin_2.0.0.0078_amd64.deb

It all went well and didn't report a similar error message.

Summarize

Installation relies on the installation of a complete, do not single installation, mainly because the package will have a certain dependence between each other, this is you can not accurately locate, it is done in one installation action.

Also note: the Linux version of the Sogou input method is currently only compatible with Ubunut 15.10, please know the situation each other week.
