ubuntu 命令行刪除apt-key

如何刪除呢？

First you need to find the key id of the key you added. Do this by the command:

sudo apt-key list

It will list all the keys that you have, with each entry looking like this:

pub   1024R/B455BEF0 2010-07-29
uid                  Launchpad clicompanion-nightlies

Once you have figured out which key to remove, use the command sudo apt-key del <keyid>where is replaced with the actual keyid of the key you want to remove from your keyring.

nits@nits-excalibur:~$ sudo apt-key del B455BEF0
[sudo] password for nits: 
OK
nits@nits-excalibur:~$ apt-key list | grep clicompan
nits@nits-excalibur:~$
