System update broken

[Kyle]

System update easily broken. Here is the procedure. And I believe this may happen to many Chinese users

I downloaded Sougou Pinyin (the most popular Chinese input app) from official website which is released the same date 16.04 is released and claims it supports 16.04.

I downloaded the file sogoupinyin_2.0.0.0072_amd64.deb, and double click to install. Then Ubuntu Software window pops up. And I click "install", then no response. And I clicked again, this time a "Waiting to install" icon appears on the sidebar but never finishes. Then I turned off my PC and turn it back on again, now I see a red icon appears on top of top sidebar near time which indicates "An error occurred. Please run Package Manager ..."

And since then I am not able to install any update.

I believe this is a blocker bug. And I have to re-install the system again.
