解决apt update执行时因签名而运行失败的问题

家里的台式机吃灰很久了,担心坏掉,近期花了点时间重新插好线,晚上下班用来查查资料,写写笔记。

当前主要使用ubuntu系统,近期更新软件包时,发现总是会报错,如下:

shell 复制代码
$ sudo apt-get update

W: Some index files failed to download. They have been ignored, or old ones used instead.

经过搜索,发现报错信息和/etc/apt/sources.list.d/google-chrome.list中的配置相关,如下:

shell 复制代码
$ cat /etc/apt/sources.list.d/google-chrome.list
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out this entry, but any other modifications may be lost.
deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

参考网友的帖子,在命令行执行如下命令。注意4EB27DB2A3B88B8B来自于前述报错信息。

shell 复制代码
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 4EB27DB2A3B88B8B
Executing: /tmp/apt-key-gpghome.PLpUkfs0hN/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 4EB27DB2A3B88B8B
gpg: key 7721F63BD38B4796: 2 duplicate signatures removed
gpg: key 7721F63BD38B4796: "Google Inc. (Linux Packages Signing Authority) <linux-packages-keymaster@google.com>" 3 new signatures
gpg: key 7721F63BD38B4796: "Google Inc. (Linux Packages Signing Authority) <linux-packages-keymaster@google.com>" 2 new subkeys
gpg: Total number processed: 1
gpg:            new subkeys: 2
gpg:         new signatures: 3

此时再次执行更新操作,报错信息消失,命令成功执行结束,如下:

shell 复制代码
$ sudo apt-get update
Get:1 http://dl.google.com/linux/chrome/deb stable InRelease [1,825 B]

世界又美好了。
