In Ubuntu, the chromium-browser package is in the Canonical Universe repository, which means that it is community-maintained rather than officially supported by Canonical.
The result of this is that the chromium-browser package is sometimes out of date, leaving you running an older version of Chromium rather than the latest stable release.
Canonical are working on entirely deprecating the Deb package and moving to using Snaps as the only official method for running always-updated Chromium. Source: https://community.ubuntu.com/t/intent-to-provide-chromium-as-a-snap-only/5987
The official Chromium snap can be found in the Snap Store here: https://snapcraft.io/chromium
To install the Chromium Snap on Ubuntu, use the following command:
$ snap install chromium
Then, when you want to check for upgrades and install them if available, use:
$ snap refresh chromium
chromium-browserThe Chromium Snap and old chromium-browser package can co-exist, as their installation and configuration directories are completely separate. The command to launch the Chromium Snap is chromium, while the command to launch the Deb packaged version is chromium-browser.
If you wish to transfer your user data (browsing history, bookmarks, extensions, etc) from the chromium-browser version to the new Chromium Snap, this can be easily done:
~/.config/chromium/, just in case something goes wrong. If you are the only user of Chromium, your user profile will most likely be a directory named Default. If you have multiple Chromium users, it may be called something else, which you can check at chrome://version under the 'Profile Path' variable.~/snap/chromium/current/.config/chromium/Default.chromium command, or by using the application launcher. In order to quickly identify which launcher is the new Chromium Snap, the Snap usually has a more modern, flat-design icon, while the old chromium-browser launcher has an older '3d' icon. This may differ for your own system though.chromium-browser package and any associated package repositories.
