Cannot download software due to password problem

[LG83]

Hi,

I've been trying to install some games from the ubuntu software center.
When I click "install" I'm asked for a password, but I don't understand why since I had my login password disabled(is it some other password?).If I just press enter without typing anything, it tells me that authentication failed.

Thanks for your help.

Software installation is a task for the superuser root.

On ubuntu, the "sudo" command is pre-configured, so that a normal user can become root by providing his/her password.

So, you disabled the question for the login password.
But you are not loging in for the software installation, you are elevating your privileges.

How did you disable your login password?
Maybe you just enabled passwordless login instead?

For disable I used: sudo passwd -d <my user>

Ok, so what exactly should I do to download software?

[LG83]

well,what should I do?

Can you still use sudo from the command line?

[LG83]

Yeah.So unless I set a password it is impossible do download new software through the GUI?

You should set the password and enable passwordless login instead.

Edit: In fact, passwordless sudo gives me chills.
