Is not in sudoers file debian как исправить

asked Dec 14, 2017 at 5:43

Open file

su root 
nano /etc/sudoers

Then add the user below admin user like below syntax.

user_name ALL=(ALL)  ALL

Both the above answers are correct as far as they go but it is easier to add your user to the sudo group in debian based systems (Ubuntu, kbuntu, debian, etc) and the wheel group under RedHat based systems (RedHat, Fedora, CentOS, etc)

usermod -a -G sudo user
or
usermod -a -G wheel user

This is a very common error for the beginners.
The error occurs because we are trying to access/update something with super privileges from the user instead of root -user.

Hence, to solve this,we need to make changes in the sudoers file where the root user has been given the privileges. So, switch to root user,run the following command

sudo su 
# vi /etc/sudoers

The editor would open the file, now scroll down to the bottom where you will see a line

#User privilege specification

root     ALL=(ALL:ALL) ALL

username ALL=(ALL:ALL) ALL

As you can see, I have just added my username with all permissions.

Save the file, and exit. Switch back to the user and start using sudo commands with ease.

Got a slightly different syntax to Rodney’s from my host

usermod -aG wheel username

Their explanation was

The user will need to be added to the wheel group.

Use the usermod command to add the user to the wheel group.

You may need to log off and log back in after doing this

1. Entered Root using command $ su root. Input Root Password

2. Install sudo: $ apt-get install sudo -y

3. Add your < username> $ adduser <username> sudo

4. $ exit

5. Then sign up and sign in the < username> session

6. Finally, check with: < username>@< hostname>:~$ sudo apt-get update

Add your user to the list of sudoers. This will make it easier to execute
commands as the user that you have created will require admin privileges.

sudo adduser username sudo

(Note:- Username is the user you want to give the privileges)

It would be something of a security hole if you could add yourself to /etc/sudoers without having sudo or root access. Basically then anyone could make themselves root.

Basically you need to ask the administrators of that machine to add you, or to install the package for you, as per the policies of the site.

You should also be sure to use visudo to edit the sudoers file — it checks that the syntax is correct before writing the file. And you can use editors other than vi with visudo. It will by default use whatever you have set as $EDITOR and if you don’t have it set you could do

# EDITOR=nano visudo

to use the nano editor instead.

Login as root and use /usr/sbin/visudo to edit the file and add your username. Normal vi/vim will not be able to edit the file.

The easiest way is to just go down until you see the line «root ALL=(ALL) ALL» and add yourself under that with the same syntax (yourusername ALL=(ALL) ALL). Or, you can read the sudoers manpage if you want to give yourself more specific privileges.

Just typed the command:

$ su

And asked for the password «root». Typed and boom… It worked!

This problem was my mistake. Due to be back at the facility at the time I created the username and password.

Perhaps the easiest way, once you’re root, is:

echo 'amarzaya ALL=(ALL) ALL' >> /etc/sudoers

If your sudoers file already contains this kind of line

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

Then, the cleanest way of doing things is probably to grant the admin group to your user. For instance, to add user oracle to the admin group:

usermod -aG admin oracle

In case you can still get root access using su, you can use this one-liner to add yourself to /etc/sudoers/:

su -c 'echo $USER ALL=(ALL)ALL >> /etc/sudoers'

To activate the change, log out and in again. For example end your the X Session or log out via shell enter exit.

If you cannot use the sudo command, then you can use the following method:

1. Press Ctrl+Alt+F1
2. Log the user out if the user is not root
3. Log in as root
4. Use root privileges
5. Log out (exit) – Ctrl+Alt+F7 to get to the GUI

Sign in using the following first:

$ su

Then go ahead with:

$ sudo apt-get update

or whatever as normal
