Apt update error - "An error occurred during the signature verification" (Chrome) [duplicate]

Solution 1:

Apparently Google changed key for Chrome Linux repo. You can fix it by importing new repo key from Google:

wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

Now you should be able to update the system without any errors.

This works for APT-based distros: Debian, Ubuntu and derivatives (Linux Mint, Kubuntu, Xubuntu, Lubuntu, etc.)

For more info and a fix for RPM-based systems (Fedora, CentOS, openSUSE, etc.) see official Google Linux repositories page.

Solution 2:

try this:

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6494C6D6997C215E

and

sudo apt-get update

Solution 3:

This should fix it for you

wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
