If you don’t want to start over just uninstall chromium and install chrome.
To uninstall the chromium-browser and xvfb packages on Ubuntu, use the following command:
sudo apt-get remove --purge chromium-browser xvfb
Then run:
sudo apt-get autoremove
Then run:
sudo apt-get clean
Then you need to install chrome by running these commands:
wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
Then:
echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" | sudo tee /etc/apt/sources.list.d/google-chrome.list
Then:
sudo apt-get update
Then:
sudo apt-get install google-chrome-stable
You can then find the app in the app library click on it and make it default.
Run this command every month or so to update and install packages:
sudo apt update && sudo apt upgrade -y
