Preferred method - installation from the Universe repository:
sudo add-apt-repository universe
    sudo apt update
    sudo apt install google-chrome-stable
    Second method - installation Google Chrome deb package
sudo dpkg -i google-chrome-stable_current_amd64.debsudo apt-get update
        sudo apt-get -f install
        And from now you can run Chrome seamlessly. The .deb package installed Chrome repository so you can
        update Chrome in standard way:
        sudo apt-get update
        sudo apt-get upgrade
    
If in your Ubuntu system does not exist Google Chrome repository file: /etc/apt/sources.list.d/google-chrome.list,
then you can add it as described below:
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
sudo sh -c 'echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
sudo apt-get update
Now to install Chrome just issue following command:
sudo apt-get install google-chrome-stable
Because Google dropped its support for 32-bit Chrome Linux versions, each apt-get update command
will spit with annoying essage:
Failed to fetch http://dl.google.com/linux/chrome/deb/dists/stable/Release  Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)
To get rid of it just do as following:
deb http://dl.google.com/linux/chrome/deb/ stable main
        add phrase [arch=amd64] between deb keyword and http://...deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main
   sudo apt-get update
The annoying message will not appear again.
