First, you need to install Google's key.
On Ubuntu 20.04/22.04:
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/google-chrome.gpg > /dev/null
On Ubuntu 14.04/16.04/18.04:
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
Then add Google's repository:
sudo sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
Update software:
sudo apt update
Install:
sudo apt install google-chrome-stable
