I'm unable to uncheck "Pre-released updates" from Developer Options in "Software & Updates" application.

When I click to uncheck the system asks for my password and after that nothing happens.

Is it possible to unable by command line or editing some file?

checkbox doesnt works

I'm using Ubuntu 20.04.

Solution:

Delete theses files ()

sudo rm /etc/apt/sources.list.d/proposed.list.save
sudo rm /etc/apt/sources.list.d/proposed.list

Restart the system Go to "Software & Updates" and the "Pre-released updates" will be unchecked.

Thanks @Kulfy
