It's also works for me.
Boot into "generic" mode, so all the changes will be saved.
In a terminal, do this:
1) sudo mkdir /etc/opt/chrome/policies/managed
2) sudo mkdir /etc/opt/chrome/policies/recommended
3) sudo chmod -w /etc/opt/chrome/policies/managed
4)cd into the managed directory, then
5) touch test_policy.json
then, edit the file
sudo nano test_policy.json
my json file looks like this:
{
"HomepageIsNewTabPage": false,
"ShowHomeButton": true,
"SafeBrowsingEnabled": true,
"PasswordManagerEnabled": true,
"HomepageLocation": "
http://www.esaa.edu.ar"
}
Pay attention to the json format, don't forget the "," separators.
In chrome, type chrome://policy/, and it will show all your changes.
The homepage setting on chrome is weird, they want you to login at google first....
