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.

-----------------------------------------------------------------------------------------------------------------------------

删除nginx,–purge包括配置文件

sudo apt-get --purge remove nginx
  • 1

自动移除全部不使用的软件包

sudo apt-get autoremove

列出与nginx相关的软件 并删除显示的软件

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

再次执行

dpkg --get-selections|grep nginx

which nginx # 不在显示nginx

这样就可以完全卸载掉nginx包括配置文件 
注意点:首先需要停止nginx的服务

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.
