Chrome on Raspberry Pi

On a Pi device, Chromium is installed by default on version 9 (Stretch) and above. To find the version run:

chromium-browser --version
Chromium 113.0.5672.95 Built on Debian , running on Debian 11

To update the browser version run:

sudo apt upgrade chromium-browser
chromium-browser --version
Chromium 126.0.6478.164 Built on Debian , running on Debian 11

What apt does is inspects /etc/apt/sources.list.d/raspi.list and uses the repo there to search for binary packages to install.

For example: http://archive.raspberrypi.org/debian/dists/bullseye/main/binary-arm64/Packages contains the link to the Chromium browswer
