Fedora :: Gnome Root Password - Authication Failure ?
Jan 9, 2010
I just did a standard install of Fedora 12 including the specification of a root password and a user ID/Password.
When Fedora starts, it accepts the password for the user ID but it shows an authorization failure for the root passwword. However, in a terminal session the root password is accepted when I enter the "su -" command.
How do I get the Gnome Desktop to accept the root password?
Related to this is an interesting security issue when I use the "su -" command to switch to the root user in a terminal session. Apparently, I do not get full root privileges as far as Nautilus is concerned. Nautilus loads but has a very restricted range of files/folders. It won't let me access "Computer" so that I can drill down through "Filesystem", etc. In contrast, Gedit run from the terminal will allow editing of all files after I enter the "su -" command in the terminal window.
I have run "yum update" to install the latest version of all packages but nothing has changed. I'm downloading the DVD image of Fedora 11 but I hate to do a another total Fedora install if I can avoid it.

have been experiencing an error (the past few weeks) whenever I try to install a software package using the default installer. Each time I enter the root password it is not accepted and I am unable to get past it and the installation fails.This is the error message that is issued:[PK_TMP_DIR|dir:///var/tmp/TmpDir.mf2zCf] Repository already exists.I am able to enter the root password in a terminal session without any problem along with using the Install Software option in the main menu.

I have installed Ubuntu 8.04 inside windows and every time I go to the terminal and type "su" it asks me for a password. Well the password I set before the install doesn't work, it gives me an authentication failure. I thought that since it was inside windows it didn't set me as a root user. I go to user groups and I see my name there and then "root" above it, but its grayed out. Is there a default root password I can enter?

My system software is installed on an encrypted LVM on hda1 and hda2. My home directory takes up the whole of hdb1 which is also encrypted. I can boot up into the kde desktop okay, but when I open up konsole and type 'su' and my root password I get the message "su: Authentication failure". I am absolutely certain that I am using the right password.
Even more strangely, if I fire up synaptic and give it that same password I am able to install software. Does anyone have any suggestions as to what's gone wrong and how I can fix it?
I can also type Ctrl-Alt-F2 and log in as root to do administrative tasks without any problems so I cannot understand why konsole has locked me out.

When I try to do software updates in Debian Gnome 7.8 it asks for my root password. I try my usual login password but it does not work. I don't recall setting two different passwords when I installed Debian. What can I do now?

I have a minor problem with my "Update Applet 2.28.0" in Gnome. It occurs when I want to make the applet do one or more suggested update(s). It always asks me for the password of superuser/root: "Authenticate : Authentication is required to update packages. [...]". I think under my installation before (11.1 maybe updated from an older version) I could tell the automatic/semi automatic updater to remember the su password (in YaST or in the authentication dialog?).
In the help manual on my computer (and in the internet) there is the possibility to make the updater remember the password via policy kit: ("Access to all privileged operations is controlled via PolicyKit." See: GNOME Documentation Library : gnome-packagekit Manual : Introduction) I could not find any policy kid or any other possibility to give to the automatic updater (or its user) that privilege permanently (=to remember authorization). I think on a system with more (real) users this could be a real problem (not just an inconvenience).

I just installed Fedora 12 on HP Pavilion (dual boot with Windows vista). I made it all the way through the installation and created my user account. A few seconds later I got the login screen asking for my password. I enter the password and get "Authentication Failure."
The name that shows up on the login screen is my full name, not the user name that I created. Is that wrong?

When I installed the OS, I wasn't prompted to set the root password. Is this a bug, or did my install hose up?

I have installed fedora 14 in my computer. I installed some applications from root. I created a user id. I am unable to install my internet (broadband connection) now. every time it shows the error "Authentication failure" "install from root" something like that. How can I switch between user and root. Or how can I login as root again?

I just got Fedora 12, and I used su root to change the bin ownership to my primary developer account. For some reason, though, all subsequent attempts to log in as root have had authentication failure, be it through su or through the startup login screen. This does NOT occur for adminstrator tools such as Groups and Users.

I found this on Bee's website. For more info on this exploit there are links there:[URl]..All you have to do in Fedora 13 is enter the following lines in a shell as normal user:
[Code]...
I don't think this can be considered solely an "upstream" problem, because I first tried it in Arch using the same version of glibc, and the final command causes both gnome-terminal and xterm windows to disappear.

I'm a long time Linux user. Finally got around to upgrading my Fedora 11 system to Fedora 12 by using the 'preupgrade' tool. The upgrade appeared to go well (downloaded packages, rebooted into installer, etc). However, now that the upgrade is complete, I'm unable to boot my system.
Here's my configuration:
/dev/sda (80Gb)
200Mb /boot partition (ext3)
52Gb / partition (ext4 - managed as logical volume)
2Gb swap partition (managed as logical volume)
20Gb /spare partition (ext3 - managed as logical volume) .....
All worked fine under Fedora 11 for the last few months. Grub now presents me with 'Fedora' and 'Windows XP' boot options. The /boot/grub/menu.lst file is essentially the same as it was for Fedora 11, except for the different kernel versions, etc. The boot sequence shows the Fedora bubble (??) and gets about 80% full when the screen goes black and the message displayed is:
No root device found
Boot has failed, sleeping forever
If I boot Windows, all works fine.
Am able to boot using a SystemRescueCD disk. The disks all look okay and I can mount/modify all partitions, etc. The grub menu.lst file read as follows (sorry, typed in, not copied):
default=0
timeout=10
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.32.11-99.fc12.i686.PAE)
root (hd0,0) .....

I got during my last year of high school, and I recently installed Fedora 11. During the installation, I misunderstood one of the questions, and set my root password as what I wanted my account password. I want to go in and change it, because it's pretty easy to figure out and has me feeling really vulnerable, but it won't let me. I went to System-Administration-Root Password, entered my password, and put in a new one, but it won't let me click Change Root Password. The button is faded out and unclickable. I've tried several different passwords, and triple-checked each to make sure I typed it in correctly, but it won't work.

I am trying to su from liveuser to root to run yum update. If I am not root, I get a message that says "need to be root to perform this command". I am logged in as liveuser. If I do an su root then it says that my password is invalid. Since I did not set up the root user, I do not know the password.

I have, on numerous times, tried to set up a wireless printer using CUPS. with each attempt it repeats a query asking for the username and password (root password). After entering both the window disappears, pauses and again repeats the same request. It appears that it will not accept the root password even though it works in other cases such as becoming a root user.

just installed fedora 15 on my dell inspiron mini 10. I used the livecd to install it to the harddrive with the wizard. I need to use the root account to get the yum to install the wifi drivers and such. i set the root password as "root01" the first time. it didnt work so i figured maybe i made a mistake. so i reinstalled it making sure i used "root01". it still doesnt work. anybody had this problem or heard of this problem before? i am under the impression that the passwd file could be recovered by using Grub to load it under a singleuser setting. however grub wasnt installed

I want to verify the root password. I am using rPath linux and my use case is like this: 1. There is screen in my application through which user can change the root user's password. He provides 2 information in the screen
i. existing password
ii. new password
2. I use a shell script in the back end that uses the "passwd" command to do it. And it doesn't ask for the existing password. But, my business use case is if user enters wrong existing password, I should not reset the password and throw some error message. How do I verify the existing root user's password? And also keep in mind that I am already in that linux box (logged in as root). Also let me now if there is any smarter way of doing it other than "passwd" command.

The printer configuration dialogue under Fedora 13 KDE will give the error message "The password may be incorrect" when I click on the new network printer button, however there was never anywhere that I entered a password. The configuration will continue after this but it will throw an error that it doesn't have permission to do what it needs later on. I have been searching for a bug but have not been able to find one. This is reproduceable on both Fedora 13 machines I am running.

I have winbind Active Directory authentication set up on my laptop. AD authentication works like a charm, passwords cache, etc. I can use sudo with no problem. However, I cannot use the root account -no matter what I set the root password to, the system will not take it. I also have a couple of normal system users (not winbind), and no matter what I set their passwords to, I cannot login.

Forgot root password on fedora 10. Reboot into runlevel one and changed passwd and it said all tolkens updated. Typed exit and it didn't reboot and at login screen I logged in as other "root" and it didn't work with new password. So I redid the runlevel 1 and password change and typed init 6. It didn't work after that also. How to change fedora 10 root password if the old password is forgot?
