Kali_linux_apt Get_update报错gpg Error的解决方案

 
  • Feb 17, 2018

阴历年后第一篇，发现Kali Linux的apt-get update报错

    Err:1 http://mirrors.ustc.edu.cn/kali kali-rolling InRelease
    The following signatures were invalid: EXPKEYSIG ED444FF07D8D0BF6 Kali Linux Repository <devel@kali.org>

  1. 使用apt-key list来查看下，发现有个keyring.gpg 过期了

     apt-key list

 #省略n行
 /etc/apt/trusted.gpg.d/kali-archive-keyring.gpg
 -----------------------------------------------
 pub rsa4096 2012-03-05 [SC] [expired: 2018-02-02]
       44C6 513A 8E4F B3D3 0875 F758 ED44 4FF0 7D8D 0BF6
 uid [ expired] Kali Linux Repository <devel@kali.org>

解决方案如下：

  1. 下载新的文件:

     wget https://http.kali.org/kali/pool/main/k/kali-archive-keyring/kali-archive-keyring_2018.1_all.deb

  2. 安装下：

     apt install ./kali-archive-keyring_2018.1_all.deb

  3. 验证安装：新的expires: 是2021年

    apt-key list

#省略

/etc/apt/trusted.gpg.d/kali-archive-keyring.gpg
-----------------------------------------------
pub rsa4096 2012-03-05 [SC] [expires: 2021-02-03]
      44C6 513A 8E4F B3D3 0875 F758 ED44 4FF0 7D8D 0BF6
uid [ unknown] Kali Linux Repository <devel@kali.org>
sub rsa4096 2012-03-05 [E] [expires: 2021-02-03]

  4. 删掉了一个历史遗留keyring:

     /etc/apt/trusted.gpg.d/sogou-archive-keyring.gpg
 ------------------------------------------------
 pub rsa4096 2014-04-09 [SC]
       6CE3 5A4E BAB6 7609 4476 BE7C D259 B755 5E1D 3C58
 uid [ unknown] Ubuntu Kylin Archive Automatic Signing Key <council@ubuntukylin.com>
 sub rsa4096 2014-04-09 [E]

 #以前安装搜狗拼音的时候遗留的产物。

 apt-key del "6CE3 5A4E BAB6 7609 4476 BE7C D259 B755 5E1D 3C58"
 OK
