http://dl.google.com/linux/chrome/deb/ automatically added to sources.list

Description

Originally reported on community

When running sudo apt update I started wondering about multiple warnings on target packages being configured multiple times. I thought that I had accidentally added the Brave repository multiple times, but then I discovered /etc/apt/sources.list.d/brave-browser-dev.list with contents:

### THIS FILE IS AUTOMATICALLY CONFIGURED ###

deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main     

Steps to Reproduce

1. Install Brave from terminal by adding sources
2. Enter cat /etc/apt/sources.list/brave-browser.list in terminal
3. Shows Google link automatically added to sources.list file

Actual result:

Expected result:

Should not add it

Reproduces how often:

Brave version (about:brave info)

Reproducible on current release:

Yes for all brave release/beta/dev

Website problems only:

• Does the issue resolve itself when disabling Brave Shields?
• Is the issue reproducible on the latest version of Chrome?

Additional Information

What is happening is that the .deb / .rpm packaging that comes with Chromium includes a cron job that runs once a day and adds the chromium repository (or re-adds it if it has been disabled). This happens at most 24 hours after installing the package and so it’s not immediately obvious after installation.

If you want to get rid of it, you need to remove the repository, but also the cronjob in /etc/cron.daily/ to prevent it from re-adding the repository. My pull request removes that cronjob so that the Chromium repo never gets added.

This issue also affects /etc/apt/sources.list.d/brave-browser-beta.list.
