You might want to look at ungoogled-chromium,[0] there are downloads for most non Windows platforms. Also packages are available in repos for apt/deb, yum/rpm, etc.
Besides, there are quality concerns with browser forks maintained by an understaffed project. The fact that ungoogled-chromium asks for internet randos to provide its own binary releases doesn't inspire confidence either. If someone desperately needs to use Ubuntu, they'd be better off using Firefox.
