If you are a chromium user for years, you may want that default chromium from ubuntu repo experience. One may feel that installation from Debian Buster repo is safe among the options, but that package is not stable at all. However none of the official solutions gives optimal chromium experience we had in previous distros. Which not only blocks default ubuntu installation, but also gives some directions on installing chromium as the description of the package. To remove any further complexities, Linux mint 20 uses a dummy package “chromium-browser” from ulyana repositories. Since Linux mint removed snap support in Ulyana, it is not possible to install Chromium browser from ubuntu repositories. Linux mint developers believe that it is unethical to use such a contraversial package management system like snap without end user’s explicit approval. Ubuntu now uses snap installation of chromium even if you are using APT. As you may know, Ubuntu 20.04 is the base package of Linux mint 20.

This is mostly because of ideological conflicts between Linux mint developers and Ubuntu developers. Installing Chromium in new Linux Mint 20 is not as easy as before.
