View 10 Replies View RelatedI have pc/os linux 2009 installed and I recently got the following message while trying to boot up my system:
*checking root file system...fsck 1.41.4 (27-Jan-2009) dev/sda1 contains a file system with errors, check forced. /dev/sda1:Inodes that were part of a corrupted orphan linked list found. /dev/sda1:Unexpected inconsistency;run fsck manually. (i.e., without -a or -p options) fsck died with exit status 4
*An automatic file system check (fsck) of the root filesystem failed. A manual fsck must be performed, then the system restarted. The fsck should be performed in maintenance mode with the root filesystem mounted in read-only mode.
*The root filesystem is currently mounted in read-only mode. A maintenance shell will now be started. after performing system maintenance press Control-D to terminate the maintenance shell and restart the system.
Give root password for maintenance:
The problem is, when I enter my password I get an incorrect password prompt. How can I change my password so that a manual fsck can start? Why did this message error message appear in the first place?

I don't know if this is supposed to happen or not.I've found a bunch of different sites on the Internet that explain how to change the root password, but none of them seem to work for my specific work station.
I've got Ubuntu 9.10 64 bit. In the GRUB boot menu, I can choose to boot normal or in recovery mode (I'm led to believe older versions don't have this option).I've tried typing # sudo passwrd into Terminal, but I already have a root password set up apparently, so I can't change it there.
At the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.

So i have a fresh install of the server edition of Karmic, i'm running the Xfce desktop. When I attempt to manage users and groups through the GUI, I am prompted for what I think is the root password, the reason I say this is because the account I am currently logged in has sudo privileges and it does not accept that password at all, but I read that by default the root account is 'locked,' (to be honest it was so long ago since I last installed Ubuntu I completely forgot if it is or isn't, my current desktop installation has su access) is it asking for the root password? why doesn't my current user account password work if the root account is 'locked'? I can perform all other administrative tasks with sudo no problem.
the funny thing is, I have the exact same setup in a virtual machine, the same problem happens, except for some strange reason after changing the password on the only account (besides root), the password required to administer users and groups stayed the same after the change. (at the time of installation I just put both the user and root password the same and now that it is setup), i'm now ready to change the passwords. except now I read that the root account is locked by default, but this strange problem occurs.

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.
