var/cache/apt/archives occupying huge space
I am in the process of cleaning up my system. And I see a lot of space occupied by this folder /var/cache/apt/archives (1.5GB). Is it absolutely necessary to keep all these archives?
You don't need to keep them around if you don't want them. Executing a
sudo apt-get clean will clean out the directory.

刪除nginx，–purge包括配置文件
sudo apt-get --purge remove nginx- 1
自動移除全部不使用的軟件包
sudo apt-get autoremove列出與nginx相關的軟件 並刪除顯示的軟件
dpkg --get-selections|grep nginx sudo apt-get --purge remove nginx sudo apt-get --purge remove nginx-common sudo apt-get --purge remove nginx-core再次執行
dpkg --get-selections|grep nginx which nginx # 不在顯示nginx這樣就可以完全卸載掉nginx包括配置文件
注意點：首先需要停止nginx的服務
sudo service nginx stop

What is the best way to uninstall nginx
sudo apt-get remove nginx nginx-common # Removes all but config files.
sudo apt-get purge nginx nginx-common # Removes everything.
sudo apt-get autoremove # After using any of the above commands, use this in order to remove dependencies used by nginx which are no longer required.
