According to [ https://support.google.com/chrome/a/answer/9844476?hl=en#zippy=%2Clinux ] If you have Microsoft® Windows®, Apple® macOS®, or Linux® devices that are no longer being used in your organization, you might decide to repurpose and distribute them for personal use. Or, some users might purchase a second-hand Windows or macOS device, where Chrome Browser was previously managed by an administrator in a school, company, or other groups. If devices are not properly reset, Chrome Browser might still be managed by an administrator.
To remove this on Linux, in my own case I used Fedora 32 - navigate to /etc/opt/chrome/policies/ and delete the files inside the policies directory.
Aww! Wait a minute, you couldn't delete that, right? Yes, you can't use the conventional way of deleting files to do that.
Okay, for us to delete the files/folders, right-click inside the policies folder and select open in Terminal
Yes! You got it, now login as an administrator using
sudo su
and type in your password.
Wait, let's confirm you're in the right directory, type ls for us to be sure the files/folder we want to delete is actually what is listed or showing.
Confirmed! Okay now type
rm -rf <file(s)_or_folder_name>
where rm -rf : Force deletion of current folder and sub folders in my own case it's rm -rf managed
OMG! It has deleted... wow
Now, let's open the Chrome browser, awesome! The "Your browser is managed by your organization" is no longer there.
You just did it!
