When I try running applications or using sudo in konsole, the prompt sometimes asks for the user password, and then responds that it's not a sudo or administrator password.

It used to only ask for an administrator password.

It does sometimes ask for admin authentication. Additionally, it won't let me download from discovery any more.

I created a new user to check and the new user works like my current user account used to. I need the admin password to do certain actions, and it will always accept the admin password.

The one post I can see from before is sudo not asking for password of correct user but it's almost 10 years old, and as I can see that I can use the admin password in other situations it'm not sure it applies to my situation.

    I don't think that the password management for sudo has changed. In order to get elevated permissions (alias administrator's privileges), you should run sudo command and enter the password of your user (the same password used to log in). The settings in all Ubuntu flavours is that you cannot log in directly to the user root and there is no separate administrator password. – sudodus Dec 16 '21 at 11:35

    If you want to run as root, please be aware that it is risky. You can use sudo -i – sudodus Dec 16 '21 at 11:38

    Please post the exact commands you are typing into the Konsole and what is the exact output. sudo is expected to ask for your user's password. – Piotr Henryk Dabrowski Dec 16 '21 at 12:30

    Maybe another program (maybe even another computer for example the router) is asking for the administrator's password. – sudodus Dec 16 '21 at 14:09

    So since the initial post, without changing any settings that i'm aware of, i can now run programs and install/update from discover. I have no clue why.

    someone asked what commands i ran, it was sudo blob obviously blob isn't a command, it was purely to test what was happening with sudo, it is still asking for my user password, although i can see that i would need to add myself to sudoers to make that work

  • @Plum, what you observe in this recent comment are normal features of sudo. You can run any command with sudo, and it means that you run it as the user root instead of your normal user ID. But for security reasons (to avoid damage by mistake) it is a good idea to use sudo only when necessary, that is when the normal user ID has no permissions (either to run the program or to read or write a file or a combination of those restrictions). – sudodus Dec 17 '21 at 19:17
