Google Chrome is the most used Internet Explorer software on the earth, with a recent update in 2021 that Chrome is currently the primary browser of more than 2.65 billion internet users; as you would know, installing Linux Mint, like most Linux distributions, only install Mozilla Firefox. However, installing Google Chrome on Chrome is a straightforward task.
In the following tutorial, you will learn how to install Google Chrome on Linux Mint 20 LTS release series in three alternative ways: stable, beta, or unstable versions, along with some essential command tips for users.

Update Linux Mint
First, update your system to ensure all existing packages are up to date.
sudo apt update && sudo apt upgrade
Install Required Packages
To successfully install the browser, you must install the following packages; run this command if you are unsure; it will not harm your system.
sudo apt install software-properties-common apt-transport-https wget ca-certificates gnupg2 -y
These are pretty generic dependencies that may be already installed. Run the command regardless if unsure, as many other installations will require these on your system.
Install Google Chrome Browser
Import Google Chrome GPG Key
The first step in installing Google Chrome is to import the GPG key for the digital signature; without this, your installation will not complete successfully.
Import the GPG key, and use the following command.
sudo wget -O- https://dl.google.com/linux/linux_signing_key.pub | gpg --dearmor | sudo tee /usr/share/keyrings/google-chrome.gpg
Import Google Chrome Repository
Once the GPG import is complete, you must import the Google Chrome repository.
echo deb [arch=amd64 signed-by=/usr/share/keyrings/google-chrome.gpg] http://dl.google.com/linux/chrome/deb/ stable main | sudo tee /etc/apt/sources.list.d/google-chrome.list
Install Google Chrome – Stable
The next step is to update the repository list using the apt update command to reflect the new additions to the apt sources list.
sudo apt update
Next, install the Google Chrome stable edition, the recommended option for most users.
sudo apt install google-chrome-stable -y
Install Google Chrome Beta / Unstable
Alternatively, you can install Google Chrome Beta or Unstable. These two versions are not recommended for daily use, especially not on a main desktop or production server. However, you can install alternative versions for those who want to live on the edge.
Install Google Chrome Beta
sudo apt install google-chrome-beta -y
Install Google Chrome Unstable (Nightly Build)
sudo apt install google-chrome-unstable -y
How to Launch Google Chrome Browser
With Google Chrome installed, if your terminal is open, use the following command to launch the browser.
google-chrome
For most desktop users, you would launch the browser using the following path to the application icon.
Activities > Show Applications > Google Chrome
Alternatively, use the search function in the Show Applications menu if you have many applications installed.
Example:
The first time you open Google Chrome on Linux Mint, you will be greeted by the following pop-up.
Example:

Untick or leave as is by setting Chrome to the default Browser over what is typically Firefox, along with the option of sending Google data and crash reports.
Click the OK button to continue.
Next, you will be prompted to sign in, skip this, or sign in optionally.
Click on the X in the Chrome Browser tab to skip.
Example:

Congratulations, you have installed Google Chrome on your desktop.
How to Update/Upgrade Google Chrome Browser
Ideally, you should check for updates using the terminal often; sometimes, the GUI update notifications may update Google Chrome; run the APT update command in your terminal.
sudo apt update
If one is available, use the upgrade option:
sudo apt upgrade
Note this will update all packages (recommended), for example, to upgrade the Chrome package.
sudo apt upgrade google-chrome-stable
How to Uninstall (Remove) Google Chrome Browser
Remove Google Chrome Stable
Remove the browser using the following command for users no longer interested in the stable Google Chrome Browser.
sudo apt autoremove google-chrome-stable --purge
Users who have installed the non-stable versions use the following command to suit your installation.
Remove Google Chrome Beta
sudo apt autoremove google-chrome-beta --purge
Remove Google Chrome Unstable (Nightly Build)
sudo apt autoremove google-chrome-unstable --purge
Next, remove the repository that was imported with the following commands.
sudo rm /etc/apt/sources.list.d/google*
Lastly, remove the GPG key.
sudo rm /usr/share/keyrings/google*
Troubleshooting Multiple Sources.list
Please note you can install all three. However, each installation will create a new sources list in your /etc/apt/sources.list.d/ directory. When you use the apt update command, you will have multiple sources.list for Google Chrome, and some will be ignored.
Just remove the extras and keep the original one. If you accidentally delete them, copy the import directory code in this tutorial.
Example of a quick fix.
sudo rm /etc/apt/sources.list.d/google*
Then re-add the one repository.
echo deb [arch=amd64 signed-by=/usr/share/keyrings/google-chrome.gpg] http://dl.google.com/linux/chrome/deb/ stable main | sudo tee /etc/apt/sources.list.d/google-chrome.list
Remember to run an APT update.
sudo apt update
This should fix the issue in the future, and you will still receive updates for all three browsers.
Comments and Conclusion
Overall, Chrome is the most used browser, with 70% of users using it. Remember, it is probably one of the most targeted Internet Browsers for zero-day exploits. Keep it up to date, and you will be fine.
