I am trying to use the terminal in Fedora but it won't accept my password.

james frankham · 06-15-2015, 06:13 PM

I have only just installed Fedora and am trying to get updates via

sudo yum update

and it won't accept my administrator password that I created on installing fedora.

Sorry, try again.
[sudo] password for tbird:
sudo: 3 incorrect password attempts.

Is my sudo password my administrator password or the password I use to log in. None of them work.

Sudo would expect your normal user's password, and that user must be enabled in the /etc/sudoers config file.

I am not sure how Fedora assigns sudoers by default, different distros do it differently.

If the user is not in the sudoers file the error sudo outputs is to say so and zay that it will be reported not say that the password is incorrect, this may be bad syntax in the sudoers file, it's quite picky about syntax, can you post the sudoers file? after removing any sensitive bits.

"Is my sudo password my administrator password or the password I use to log in"

User's password. But you could have tried that.

It's not the users password

james frankham · 06-15-2015, 07:43 PM

/etc/sudoers config file.

does anybody know where I find this sudoers file.

On F22 (which you should have installed if a recent install), you should get nag screens for using yum instead of dnf.
So I'll presume you're pre-F22.

I don't use sudo normally, but (in F22) it all looks like the above if you use the wrong user password.
The default sudoers file only has the wheel group (other than root) as authorised to all commands. If you didn't tick the box to be an admin, you probably aren't in the wheel group - "groups" will tell you.
As for sudoers, start with the manpage. As usual.

Infact it is F22.

[bigbird@localhost ~]$ [bigbird@localhost ~]$ sudo yum update
[sudo] password for bigbird:
bigbird is not in the sudoers file. This incident will be reported.
[sudo] password for bigbird:

That is the output when I enter my log in password so it seems I'm not in the sudoers file.
I am very new to F22

Hi, you need to obtain superuser privileges with "su" - this does ask for your root password:

Quote:

[tim@lizard ~]$ su
Password:
[root@lizard tim]# visudo
visudo: /etc/sudoers.tmp unchanged
[root@lizard tim]# exit
[tim@lizard ~]$

Once you have the # prompt visudo takes you to the sudoers file wherever it lives. I usually search for "root" until I hit this line:

Quote:

root ALL=(ALL) ALL

I then duplicate that line and, in the duplicated line, replace root with your username.

after saving this file you have sudo privileges. Exit superuser and return to your normal login

HTH

As said previously, Fedora doesn't have sudo configured by default. You can run the commands by using

su -c 'yum update'

you might want to do some research and READING on the operating system that you installed

Fedora DOSE NOT!!!! use " sudo" by default !!
-- and NEVER WILL !!!!

if you want to use sudo, YOU have to set it up

fedora like RHEL use "su " and " su -"
and that uses the ROOT password

And every other Linux distribution under the sun, except Ubuntu and its derivatives.

You can add yourself to sudoer's as noted by a gui.

You can switch user to any user with privileges with su command. su alone is default to root. If you switch user then you'll have to supply the password for the user you selected.

I generally never run as su except in times when you have to fix a goofy distro to accept sudo.
