Ubuntu :: Authentication Failed In Software Center?
Jun 10, 2010
I apologize first because I do not know if this is the right section for my problem, but I could not find anything more suitable. I have an Asus 900 with Ubuntu Netbook Remix 10:04 In a nutshell: I realized today, trying to install a new program with Ubuntu Software Center, that I can not anymore authenticate myself as root. Of course I have not changed the password, but the old one is not anymore accepted ("Authentication failed").
The interesting thing is that I can install programs without problems (using the same old password) with the package manager in Administrative Tools (synaptic). Here, the authentication works well. Opening a terminal, I can use sudo to run any command by providing my password, with no problem at all. Following some guides found on the web, I reset the root password (supplying the same one as before) and everything went well. Only .... nothing has changed! Ubuntu center software authentication always fails.
What could have happened? Maybe I did some mistake by editing /etc/sudoers to solve another problem some days ago. Ubuntu told me that my username was not in the sudoers file, so I resolved it by adding to /etc/sudoers the line myusername ALL = (ALL) ALL
I checked the contents of the file and, apart from this line added, it is as it was before (I compared with that on another PC with Ubuntu). Can anyone make some sense out of it? Starting from the fact that the package manager does function ... but software center does not.
I have a problem with the ubuntu software center. I can't get authentication to work to install anything. The error I get is:Previous Installation hasn't been completedThe installation could have failed because of an error in the corresponding software package or it was cancelled in an unfriendly way. You have to repair this before you can install or remove any further software.I have no idea how to "repair this". I was trying to install XML copy editor and something happened during installation. Since then I rebooted but nothing seems to fix the error. I looked through the installed software and couldn't find program.I looked for some script solutions but they were for specific programs, not for the software center itself
I've been using Ubuntu since 6.04, not a linux guru by any means but can usually get myself out of trouble.
So, the issue... I installed 8.04 on my mother's laptop some time back as she was having trouble keeping Win 2000 running (she has a low spec no-name generic laptop btw). I live in Autsralia and she in England, i thought i could better support her if she was running Ubuntu... All has been well with 8.04 but with the new LTS release (10.04) i thought i'd talk her through the upgrade... Did the online upgrade via Update Manager, all seemed to go OK but when she went to log on after restart she got an error saying 'authentication failed' even though we are 100% sure we have the user name and password correct... Tried to do a ctrl+alt+F1 to by pass the GUI log on but couldn't get the terminal session to open up, just got a black screen - no command prompt.
So... thought OK re-install... downloaded the ISO, burned and sent her a CD in the post... talked her through the re-install, all seemed to go well (again) - BUT, after restart, couldn't log in "authentication failed" again...
So, remember i'm trying to talk a novice through all this... any thoughts!?!
If i can get her to log in i can then support her via some kind of remote sesion or other screen share... and it wont cost me a small fortune in international calls!!! But if i can't get a log in, i'm dead in the water!?
This is the error message I got today when updating. patch:yast2-control-center-4200.noarch conflicts with yast2-control-center-qt.i586 < 2.20.2-1.3.1 provided by yast2-control-center-qt-2.19.3-6.1.i586
I have been used NX client on windows 7 connected to ubuntu with NX client/node/server with no issues. The matter started when I have formatted Ubuntu and reinstalled NX, from that NX connects but shows a key error as follows:
NX> 203 NXSSH running with pid: 4328 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files
I just finished following the instructions found here to install FreeNX on my ubuntu 10.04 server. It went smoothly, just used the default keys.Once I had that all set up I scrolled down and followed the instructions to set up the client and that went fine as well.My problem is with actually using the program.When I try to log in I get the error "Authentication failed for user tony" (my username). Do I need to change anything in the configuration other than setting it to use gnome and putting in the host address?oes it make a difference that my ssh settings only allow rsa login? I logged into the server with ssh to see if that helped but it did not. I even tried using the ssh key with the FreeNX Client but that did not work
the laptop of my friend runs ubuntu through wubi. The system suddenly freezed and she restarted it manually. After doing a check disk and automatically repaired some packages(unfortunately she doesn't remember what exactly, only just inode information appeared), she can't log in as when she types her username and password the answer is authentication failed. We tried to change the password through recovery mode but nothing happened.
1. Do you have something to propose to solve the login problem? 2. If not how can i access and back up her ubuntu documents through windows?
I want to use nomachine, instead of freenx, and well it isn't working. SSH server works and all, because freenx works., same for neatx. But I hear with nomachine you can see the main display of the computer? Is this true? Well one way to find out, but whenever I try to login I get: Authentication failed for user x. I don't know why, neatx and freenx worked, even x2go, but not this.
I have just installed Fedora 15 on my laptop, Now i am trying to install some programs like .... skype, drivers to my printer etc but i get this message: Failed to obtain authentication.... when the installer is trying to solve dependensies...
I have tried to log in as su but i cant that ether due to fail password or username... that is the message i get at the log inn screen.
Earlier today I was setting up ssh on a new computer. I modified permissions on the Passwd folder to complete the setup. I few hours later when I went to sudo something in the terminal I received the notice of an incorrect password (after using sudo prior to this), even though it was typed correctly.
I tried to restart the computer to solve the issue, but was met with an Authentication Failed message, regardless of the user I tried to log in with. I was hoping I could log in with recovery mode but was unable to do that as well. I have searched a substantial amount and have not found a solution. Could this be an issue with permissions on either the Passwd or Shadow folder? If so, could these be changed if I ran a Live CD?
I have a problem updating packages when using the kpackagekit systray notifier, it fails with the error "failed to obtain authentication".I've looked around and can't find any log output of this.If i start kpackagekit from the menu it all works fine, but not this way.This is with kubuntu 10.10, upgraded from 10.04, it did actually work before.
I am trying to setup Postfix along with dovecot on RHEL4. I have done the necessary settings in dovecot.conf, yet I am not able to log into the POP3 server. The error I can see through WireShark/Ethereal is "Err- Authentication failed" Some of the important settings in /etc/dovecot.conf are
i am using fedora 12(32 bit),when i tryed to uninstall program pidgin from system->administration->add/remove programs i got an error message saying tat YOU FAILED TO PROVID PROPER AUTHENTICATION,so i was jst wondering if we can sign in as root through gui.the problem with my pidgin app was that whenever i tryed to start that application, it appears for like 4-5 sec and then disappears! so i thought of reinstalling the pidgin.
Im using CenOs 5 and have install a mail system(postfix+dovecot),when I trying to enable selinux for enforcing mode and i'm have some issue, the user authentication failed. How can i to fix this problem?
Above mentioned is my configuration. when i try to connect client with SSH it is not sending a request for authenticating user to RADIUS server. what else configuration i have to do, or if there are any mistakes in my configuration
If your machine is connected to the Internet, you'll probably want to disallow ssh password authentication (which is advised but not mandatory). Edit the /etc/ssh/sshd_config file and change/add the following lines:
PasswordAuthentication no AllowUsers nx
Don't forget to restart the sshd daemon after making that change: service sshd restart I already have PasswordAuthentication yes in my file as I need it to login to the server through ssh. Do I just skip that line and only add AllowUsers nx mynxuser at the end? Also, I followed the rest of the manual and when I tried the client on Windows it failed: I put in a user and password to login but shouldn't it be using the key instead? I think the problem is related to the above due to:
NX> 203 NXSSH running with pid: 1428 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files
I spend all day, trying to make bluetooth working with my phone Nokia 2600. First, i try'it with bluez-utils 3.7, and later with 3.9, but i no luck. So, what i have. I use hcitool to scan for my device, and find'it. Next, i connect to my phone with success. Then i try pairing with my phone, using "auth", but here i got error: HCI authentication request failed: Input/output error
i seem to encounter lots of little troubles here and there... just need to get used to it.
now i`ve downloaded skype for opensuse and when i dbl click on it, it says: "you have failed to provide correct authentication please check any password or account settings" but it doesnt ask me anything before the error..
I'm extremely new to SuSE Linux. I wanted to move away from Windows and so I decided to reload my Desktop with SuSE linux.I have had no trouble until now. I'm trying to connect to my work VPN connection. From my laptop (which unfortunately is Vista) I'm able to connect without any issues. However, when I tried out the KVPN application on my SuSE linux, it just doesn't work. I get the error: Authentification has failed. As a side note, when I type ping google, the packets are received 100% but when I ping my company address, no packets are received. Hope this info is useful.
I was trying to install winbind on a RHEL5 machine and I had to reboot the RHEL machine. When it came back up, I'm not able to log in as root or any other user.When I use root and give a random password, it says invalid username or password but when I use the correct password, I get an Authentication failed pop up box (under GUI). SSh window says invalid password for random passwords and the SSH window disappears when I type in the right password.Can you please let me know if I can somehow get back in by stopping any of the services
