How to add user to sudoer

[satimis]

Hi all,

Just installed kubuntu 22.04. I can login but unable to run sudo. It requires adding username to sudoer. Please advise how to do it. Root password has not been created yet. Thanks

Regards

Welcome.

Two questions first:
- Is your user the only one on this machine and if yes: why is it not automatically in the sudo group? This is the default in Kubuntu…
- What do you want to do that requires the user to be in the sudo group?

It could also be helpful if you posted the output of the command groups from the Konsole terminal emulator (please use CODE tags if you do - the "#" symbol).

You don't need a root password for anything really. The initial user at installation is always in the sudo group.

You do not need to add a username to sudoer unless you're giving some user specific access to a specific program without asking for a password. In other words: A user in the sudo group can issue any command as root by prefacing it with "sudo " in the console or entering their user password when a GUI application prompts for root access. If you want to give a specific user access to some commands without total sudo access to all commands, then you need a entry in sudoers.

More details about what you're attempting and how you wish it to work would be helpful.

You are missing some group memberships - something does not seem right here.

I strongly advise against logging into the graphical user interface (= KDE Plasma) as root - if that is what you want to do. You will have a good chance to break your system.

Use the Plasma Panel's settings and the System Settings' Appearance section.
Also see the Kubuntu Manual : https://github.com/kubuntu-team/kubu...s/tag/v22.04.2

You will be able to attach screenshots, now that you have made enough posts (3?) to have this option available to you

Since these questions are off-topic I strongly recommend starting new threads
