Ubuntu Installation :: Log On Failed After Upgrade/install "authentication Failed"
May 20, 2010
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!?

I wanted to install it on a secondary computer in my house for web browsing and little-to-nothing more.
How can I fix or get around the error 'Authentication failed' when attempting to login?
I just installed openSUSE. The installation seemed to go well. After installation, everything loaded up and I was using the OS with no problems.
I restarted the computer to change my boot sequence in the BIOS. Then I got to the openSUSE login screen. I was presented with three options:
1. my username - When I enter in the password I specified during the OS installation it says "Authentication failure"
2. Automatic Login - just says "Permission denied"
3. Other... - Nothing seems to work here
How can I login?

I have a Dell Vostro v13 laptop that was shipped with 9.04. I upgraded to 9.10 and it told me it could not upgrade the kernel. The error message said something about a problem with the kernel file. I can still run the system and have not rebooted since the upgrade, but I need to be able to reboot eventually.
The System Monitor says:
Release 9.10 (karmic)
Kernel Linux 2.6.28-19-generic
Everything I have read says that 9.10 includes kernel 2.6.31. So I am afraid to reboot now.

I started the upgrade and the system is nearly completed but I there is a problem with GRUB.Most likely since I am dual boot with win7. So right now I have a pop-up message that says...GRUB failed to install to the following devices:/dev/sdbDo you want to continue anyway? ect ect ect...I have not rebooted and completed the installation yet as I figure its probably easier to fix this now while I have the full system up and running vs having to fix it via live cd.

I installed a new Ubuntu OS in my computer, (I downloaded it yesterday) on a dual boot pc (windows xp) Installation went smooth until it reached grub-pc. It was installing grub-pc (1.98 lubuntu6). It hanged there for several hours. Finally I interrupted the installation. When I went to the installed packages I got a message telling: Grub-PC 1.98 Lubuntu 6 Failed to Install or Upgrade. I'm pretty new to Linux so I know nothing about it, but I wish to go away from Windows XP.

I have installed keberos on my suse machine, but after installation now I am not able to login in it even with the root password. I search over the internet but could not find the solution. What to do now and how to configure Kerberos on a local machine with only local users authentication. I mean client and server both are on the same machine.

Now i will try to explain my problem.I just installed fresh 11.04 openSuSe 64bit.After doing all the configuration I rebooted and tried to login.Nothing happened.Googled some things, tried ctrl alt f1 and login as root, also tried to login as root, even changed my root password to be sure.Still, nothing happens, except for the thing that everytime I try to login as root it says authentication failed, but if i type my password bad it says bad password.

If I am running a script, let's say a install script. Is there a way to make Su repeat authentication rather then just returning "Authentication failed" and continuing the script?

I have configured the remote installation of Fedora 13 with kickstart with nfs installation method. All work ok until I boot the Fedora 13 client system.
Fed13 client system receives the IP address from dhcp, receives the loader, loads vmlinuz and initrd.img from tftp, load anaconda, configures the network and dev eth0, mounts nfs server to load kickstart file, loads kickstart file (language...) but when it tries to mount nfs server to install from Fedora 13 installation tree it fails.
First, I thought that I had an error on my NFS configuration but I was wrong. I opened tty with ALT+F4 on the Fedora 13 client and I sew this error:
Code:
Is this a bug or can I modify anything to correct this error? How?

I recently tried to upgrade to 10.04 and it failed somewhere on the installation process. I managed to get the machine to boot and go into gnome but now very few programs will actually launch (terminal, nautilus and firefox is about it) and the install/update software reports al sorts of dependency issues

I had installed Ubuntu 8.04 and partitioned my drive to share 500gB with Windows XP. All was good. When I saw that Ubuntu 10.01 was available I downloaded it to update the 8.04. Ididn't want to have to redo all my configurations so told installer not to update config files. No entry in GRUB no boot. Tried to re-install 8.04 to replace 10.01 and get back to intial state. Current state Ubuntu won;t boot, XP still OK but don't know how to clean up my mess. I've attached a copy of a boot info script I ran.
Code:
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> Grub 0.97 is installed in the MBR of /dev/sda and looks on the same drive in partition #6 for /boot/grub/stage2 and /boot/grub/menu.lst.

I ran the software manager upgrade/update install of 11.04. When I reboot almost immediately a quick error flashes on screen that says something like "missing prefix" then it goes to an unfamiliar menu with kernel choices that are very old and look nothing like my desktop. I think it may be some old install or something I dont know. I have an eee pc. I originally installed with WUBI but have done other kernel upgrades with no issues.

--Began with an up-to-date Ubuntu 8.04.3--64 LTS install; tar-copied everything from sda2 to sda3 and booted SDA3 so I wouldn't fry my main install:

Will attach any logs requested; but I'm about to scrap the failed install and start over, 'cuz I want to test 10.04 LTS and the new Vmware Workstation 7.1--64 beta. The only thing I can think of is that I did not boot into the new kernel ( apt-get upgrade ) before doing the dist-upgrade. I've done a few of these dist-upgrades in the past this way; 6.06-LTS to 8.04, 8.04 to 9.x, etc

I have an Proliant DL380 that I use as a home server/router that I attempted to upgrade to Lucid. The gui upgrader first attempted to upgrade to 9.10 (as expected.)
I believe grub was incorrectly installed/updated. Not quite sure if grub2 was installed. The machine boots to a maintenance prompt. The partitions seem to be mounted read-only because of errors. The grub menu only shows an 8.04 kernel choice, even though all 9.10 packages were downloaded and, I believe, installed. The gui upgrader did fail with an error right before the "cleaning-up" stage. After "messing around" with it, the upgrader said I needed to reboot. So, I did and my problems started.
I tried booting the 9.10 Kubuntu cdrom and also a Knoppix 6 CD, but neither one would boot properly (gave me a BusyBox prompt.) So, I guess they don't like the Smart Array 6.
what I could try to fix and upgrade to 10.04? I really don't want to lose my configuration files (dhcp, firestarter rules, apache, squirrelmail, NFS, etc.)

Fail to fetch 2 ppa.launchpad.net addresses and another cause the upgrade to terminate. The error messages suggest some type of network error. Should I wait a week and try the upgrade again?

i am an ubuntu nooby, out of curiosity i installed ubuntu 11.04 alpha3 last night. Yes, i will definitely never install an alpha version unless i wish to test it! Frankly said, i first installed 386 version on a notebook which runs just fine. So I thought why not install the 64 bit version on my pc.
Unfortunately, the system did not finish the first reboot in order to complete the installation. First it always stopped at "checking battery state". There, I read that this bug is already fixed: [URL]... I came across this thread: [URL]... So I pressed Alt +F2 in order to log in and performed sudo apt-get update followed by sudo apt-get upgrade. Everytime there was a new update I hoped, that this will fix the issue. But when I shutdown the system with sudo shutdown now -h and restart again there is no progress.The only thing that changed is that the system no stops at "Stopping userspace bootsplash", whatever that means?

I used Kubuntus kpackagekit to upgrade to natty. The process started well, it downloaded everything and started to install 11.04. But then all of a sudden during Installing stage I got this error message:
"Distribution upgrade process exited with code 1"
and
"Your system might be unusable".
And it sure is unusable because after reboot I can only see Kubuntu 10.10 loading screen and
"The disk drive for / is not ready yet or not present".
There also are options for either skip mounting or manually mount hard disks. I don't have a clue how to manually mount... I get same message if I try to boot to safe mode. Does this mean I have to go to clean install? I really don't want to do that because last time it took a couple of months to get ubuntu to co-operate well enough with my laptop.

Got a Netbook. No CD drive so mounted image to USB stick and booted into installer from there. Chose the option to upgrade from 10.04 LTS to 11.04 and the installer hung on removing conflicting operating system files. In the end, I was forced to restart as nothing else could be done. Now, it just boots to this:
Quote: error: no argument specified.
mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target filesystem doesn't have /sbin/init.
No init found. Try passing init= bootarg.
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash)Enter 'help' for a list of built-in commands.
I booted to the Live CD and reinstalled Grub which now brings up a list of all the kernels and Memtest but, aside from Memtest, they still all boot to this. I don't have the passphrase for the Home folder (don't even remember encrupting it!) so I tried the ecryptfs method from the live CD to get the passphrase and backup the Home folder and do a new install but there is no trace of .ecryptfs or .Private folder and pretty much everything in the Home folder is locked. Tried an fsck on the hard drive, but nothing. I do remember thinking the hard drive was referred to as hda1, but the live CD shows it as sda1. Don't know if this affects anything. I have a feeling the installer regarded the USB stick as first hard drive and got confused.

Problem with my upgrade from 10.10 to 11.04. I got the update manager to show the upgrade to 11.04 button - proceeded. It downloaded 1300 files or there abouts then did a failed to fetch http://76.73.4.58/ubuntu/pool/main/g/. I took a screen shot which left the rest out - also did a select all - copy - no paste occurred. - re-obtained. So I'm thinking that the missing files are missing on this server and my current thought is that I will go to another server and try downloading from that one. BTW did the same upgrade from 10.04 to 10.10 to be able to upgrade to 11.04 that one worked well I didn't know there was a 10.10 upgrade since I got here; there are a few problems that went away.. This upgrade only showed after changing my status to normal from long term.

Today I ran preupgrade and chose Fedora 14 instead of Fedora 15 to be safe to upgrade from 13 . After lengthy upgrade, I wan able to login but after that whenever I try to open terminal and enter su to login as root, it suddenly hangs or sometimes it hangs by itself or even hangs after reboot. So I have totally corrupted upgrade.
I read somewhere and found I can go to GRUB menu at reboot and I can choose fedora 13 from there and was glad at least I can go back to old Fedora 13 but I do have to go to GRUB menu to choose Fedora 13 every i have to reboot. Is this OK? Now in Fedora 13 I have entered command as root: preupgrade and this time I chose Fedora 15. Is this OK? I am hoping the upgrade from 13 to 15 would work.

I've just reported a launchpad bug report about my desktop system being unbootable after upgrade to lucid lynx. [URL]... I opened this thread to ask if someone else experienced a similar problem and for collecting information and workarounds (none yet) about this quite serius problem. The system has an nvidia graphic card and proprietary drivers were installed before the upgrade. However I'm not sure the problem is related to this. FYI, the system booted regularly from a usb stick with ubuntu lucid lynx. SO the problem is in the upgrade path.

I upgraded from 10.04 to 10.10 a few hours ago using the alternate CD. I selected not to download files off the internet as I wanted to do that at a later stage. After running for close on an hour performing the update, as it reached the end it gave me a message saying the update had failed and the changes will now be restored (or something like that). I clicked ok, and the update window closed. I then restarted the pc and it stopped at the splash screen. Now I cannot get it to load the desktop environment. It Jst sits at the splash screen. Pressing the power button shuts it down normally, but alt-ctrl-f1 does not open a shell.If i start up using recovery mode and then select fail safe graphics mode something comes up about a segmentation fault in xserver in I then end up at the shell where I can work from the command line, but can never get the graphical interface to work.
