Difficulty with password in Debian
 

Hi! I just got a new computer and it has Debian 8 installed. A friend helped me set up the system but I'm having trouble at log in getting the computer to recognize my password. I know I have the correct one (and the computer confirms that) but it says "the line is busy, try again later"! Nothing seems to work here. Any help would be greatly appreciated. This is my first time using Debian; I've used Xubuntu until now. I'm now working in "root" so I don't want to linger here too long. Any help will be appreciated greatly!

When I try visudo from the root terminal I get this:visudo: /etc/sudoers busy, try again later. That is the problem. I want to get out of root as I know it's not good to linger here. But I can't gain access from my user name and password.

You need to provide the exact commands you are trying to run. If you are using sudo i.e. sudo visudo then since you are already root it is not required.

Need details but I would assume that you are trying to run commands from your regular user by using sudo and it is not in the sudoers file. debian does not configure sudo by default for regular users. If that is what you are used to you can enable it but there is nothing wrong with using su. Many arguments about which is better.

Thank you for that. But the problem is more basic: when I first try to log in (where you have "name" and "password" the system doesn't recognize my password. That is why I am currently operating from root. (But, yes, I am accustomed to using sudo as in "sudo apt-get..." etc.)

While you are logged in as root, you can reset the password for your user. Assuming your username is "yuhan" the command looks like this:

Another thing to check is that you have selected the correct language on the login screen. Sometimes people think they are typing the correct password, but because the wrong language is selected, the keys aren't mapping to the correct symbols. An easy way to check this is to type your password in the Username field, so you can visually verify that you are typing it correctly (but make sure nobody is watching over your shoulder).

isn't there a contradiction?

fwiw, i have never, ever seen a message like that on a linux machine, in no context whatsoever.

Sorry about that...it wasn't an exact quotation. What I received when typing in "visudo" was the following: visudo: '/etc/sudoers busy, try again later.' But sudoers can't be "busy" because I'm the only one on this network.

The reason I say I know the password is there is because I have tried to change it, using the same password, and the computer acknowledges it is already the present password.

But back to my original point...How do I check out of root and still have the ability to get online when my ordinary user password isn't recognized? My user name isn't the problem, just getting the password to work. Thanks for your feedback!

Are you typing
sudo visudo
or just
visudo

In the man page under diagnostics it states "Someone else is currently editing the sudoers file." Have you check to see if this is true?

Lets start from scratch... When the computer starts and the login window is displayed I assume you see your username but the password is not accepted? Normally, root login via the GUI is not enabled. Did your friend enable GUI root login or are you using the command line?

No, I logged in as root so that I could get online. So in a terminal, already registered as root, I simply put in 'visudo.' No one could possibly be editing the sudoers file--this is a private computer. How else could someone other than me be editing it? And, yes, I used the command line to get on as root.

So let's say I log out as root and return to the main sign-in window which, as you say, has username and password. When I attempt to sign in and the password is then rejected...what should I do? Would you like me to attempt that? Thanks!

A few more troubleshooting ideas you can try:

1. Reboot the computer. If another process has a "lock" on the sudoers file, then rebooting might reset the lock.

2. Switch to a "virtual console" by pressing Ctrl + Alt + one of the Fn keys. This should switch you out of graphical mode into a plain text login. Can you log in as your user in a virtual console?

3. Create a new user (one way is to use the "adduser" terminal command). Can you log in as the new user?

Does this make any sense? I went to a terminal in root and added
the word 'visudo.' I received this message:

# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.

Does this provide any information about what the problem is? Thank you!

Not really since I am still not sure what you were doing before. You have been stating that you already went to a terminal as root.

What you see is that visudo opened the sudoers file using the default text editor pico.

That seems to be the default sudoers file without any modification. In any case, did you try to change your user's password as instructed in post #5?

Changed password as suggested and no difference at all. It came back "Incorrect Password." I'm not clear about what is being suggested in the previous post...

I tried the virtual console. Same thing...came back 'Incorrect login."
