问题描述
运行时：
sudo apt-get update && sudo apt-get dist-upgrade
我得到了这个输出：

有什么值得担心的吗？我再次运行命令，现在它说：

The following packages will be upgraded:
google-chrome-stable
1 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
Need to get 48.5 MB of archives.
After this operation, 4,096 B of additional disk space will be used.
Do you want to continue? [Y/n]
那么这意味着什么呢？我应该相信这次升级吗？此升级来自Google Chrome在我从官方Google页面安装时添加的PPA。
以下是有关该PPA的更多信息：
OS信息：
Description: Ubuntu 14.10
Release: 14.10
最佳解决方案
打开终端并输入以下内容：
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
这将导入Google更新的GPG密钥。
您应该能够更新系统而不会出现任何错误。

次佳解决方案
这个站点有唯一适用于64位Ubuntu 14.04 LTS的解决方案：
http://www.omgubuntu.co.uk/2016/03/fix-failed-to-fetch-google-chrome-apt-error-ubuntu
(这是一个摘要。请查看网站了解更多详情)
-
编辑google-chrome.list(假设您在稳定频道，如果没有，请参阅网站上的精选评论)：
sudo gedit /etc/apt/sources.list.d/google-chrome.list -
在打开的文本文件中编辑文件，以便该行显示：
deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main -
再次尝试更新
sudo apt-get update
第三种解决方案
这比这些解决方案更有效：
apt-key list google
您将在此列表中看到此信息，请不要[E]表示已过期并查看最后一个7FAC 5991
pub dsa1024 2007-03-08 [SC]
4CCA 1EAF 950C EE4A B839 76DC A040 830F 7FAC 5991
uid [ unknown] Google, Inc. Linux Package Signing Key <linux-packages-keymaster@google.com>
sub elg2048 2007-03-08 [E]
pub rsa4096 2016-04-12 [SC]

uid [ unknown] Google Inc. (Linux Packages Signing Authority) <linux-packages-keymaster@google.com>
sub rsa4096 2016-04-12 [S] [expires: 2019-04-12]
你现在会做：
sudo apt-key del 7FAC5991
然后你会做这些命令：
sudo apt-get clean
cd /var/lib/apt
sudo mv lists lists.old
sudo mkdir -p lists/partial
sudo apt-get clean
sudo apt-get update
完成后，您将从另一个密钥服务器执行此操作到install keyring：
wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
然后你做：
sudo apt-get update
sudo apt-get dist-upgrade
现在你已经准备好了。 🙂
