如题，解决apt update报错：W: Failed to fetch https://dl.google.com/linux/chrome/deb/dists/stable/InRelease的问题。
2. 环境
- Ubuntu 16.04
3. 问题描述
在运行sudo apt update的时候，报错如下：
Reading package lists... Done
Building dependency tree
Reading state information... Done
9 packages can be upgraded. Run 'apt list --upgradable' to see them.
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://dl.google.com/linux/chrome/deb stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4EB27DB2A3B88B8B
W: Failed to fetch https://dl.google.com/linux/chrome/deb/dists/stable/InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 4EB27DB2A3B88B8B
W: Some index files failed to download. They have been ignored, or old ones used instead.

4. 解决方案
4.1. 管用的方案
运行：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6494C6D6997C215E
sudo apt-get update
然后就没有报错了。
4.2. （在本机）不管用的方案
运行：
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
可能由于网址不可访问的原因，没能起作用。这行命令没反应。
5. 小结
扎扎实实做事。搞清楚一个个问题
