ubuntu安裝nginx，由于80端口已經被占用，sudo apt-get install nginx安裝一半異常退出，報錯誤：

　　dpkg: error processing package nginx (--configure):

　　dependency problems - leaving unconfigured

　　No apport report written because the error message indicates its a followup error from a previous failure.

　　Errors were encountered while processing:

　　nginx-core

　　nginx

　　E: Sub-process /usr/bin/dpkg returned an error code (1)

　　再往上查詢會看到錯誤

　　nginx: [emerg] bind() to [::]:80 failed (98: Address already in use)

　　修復辦法：

　　1.將80端口解綁，已占用的程序改用其他端口，將提示的錯誤解決后

　　2.運行以下命令卸載一半的安裝:

　　sudo apt-get remove nginx*

　　sudo apt-get autoremove

　　sudo apt-get install nginx即可重新安裝
