Kubuntu 18.04: superuser and normal user

Keruskerfuerst · 05-19-2018, 08:32 AM

Hello!

I have Kubuntu 18.04 installed and have changed "sudo" to superuser and normal user.
But sometimes, when system settings like SDDM background is changed, I have type in the password of normal user (but not superuser).
Instead of this, this it should be superuser password.

How can I change this?

Exactly how did you do this? You might start by reading the Ubuntu documentation on rootsudo to see how it is handles on the various Ubuntu distributions.

What I have done:
1. sudo passwd root -> now I have root and normal user
2. But now I have the problem, that some system tasks only need the password of the normal user

By default, I imagine that applications that need root privileges will ask you for your user password, unless you very specifically become root before running the relevant application. That's how Ubuntu does things.

Is there any reason that you have decided to "activate" root itself?

You can disable the root password and revert to the standard ubuntu security scheme with:

Code:

sudo passwd -dl root

The advantage to doing this is that you can follow all of the standard Ubuntu documentation (which presumes the use of 'sudo').

If you prefer to disregard the standard security scheme then please read very carefully the document that @yancek linked to in post #2.
