Software-updater doesn't ask me for root password
When I get a prompt to install new updates, it usually doesn't want any password: when I click "Install", it automatically tries to download and install them. this often happens for security updates.
why ubuntu doesn't ask me for my root password? Is this safe?
My Ubuntu: 12.10 (updated)
Re: Software-updater doesn't ask me for root password
It was changed one or two releases ago. The reason is that asking for a password might keep some users away from installing.
Only when a new kernel is offered one has to give the password. A new kernel is a more fundamental change to the system and is not considered a normal update.
You might notice that sudo apt-get upgrade does not apply a new kernel, but sudo apt-get dist-upgrade does. It's the same distinction.
