Ubuntu :: Ubuntu 10.04 Root, Bin, And Other System File Unable To Access Under Admin?
Aug 20, 2010
I'm running window xp and unbuntu 10.04. I ran into a problem where I reinstalled unbuntu by erasing old one under CD boot. During installation, it asked me to place files and i placed it in /. Now when I log in as single user (only user or other at login screen) and try to change any system files, it said I don't have permission. I can't change anything or access root file. I try chmod function and it said i don't have permission as well.

Environment: A 32-bit kernel RHEL5.3 system running on a virtual machine. The root(/) filesystem is on an LV.
Issue: Unable to resize the FS after extending the root LV since it is mounted. After extending the LV, online resizing of the FS was not supported and the root filesystem could not be unmounted while it was in use. On rebooting, I got a kernel panic error. In runlevel 1, I couldn't run chroot, couldn't find the /etc/fstab, root FS could not be mounted, fsck did not run (tried block 31 for second copy of superblock using dd count=1 bs=4k skip=31 seek=1 if=/dev/sda2 of=/dev/sda2), couldn't find any rpm on installation media to install unix-utils rpm. On running commands in runlevel 1,
I got the following output.

While messing around with file permissions and ownership of /var/www/ i seem to have locked myself out of being able to administer users on my 9.10 system.
when I go to the user administration screen in the icon with the keys is grayed out. with the message "not authorized to make changes". My account seems to have lost admin access. But, I'm the only user on the system.
I presumed I somehow changed my group status from the root group to something else
but, sudo usermod -g root [my name] just returns "no changes made"
All I can do for now is run as the su from the terminal. Is it possible to log into gnome with a root account?

I need to customize linux kernel root file system for embedded linux system. During compile time, for root file system I am able to create different user/group ex: "gnumuzic/Muzic". But I want to give access to group "Muzic" to some folders like /dev/nexig during compile time.

I have been trying to use my DS2490 USB to serial device with a Maxim .DG1921G thermocron with owfs. It is supposed to give me access to a virtual file system for the thermocrom without needing to launch owfs as root.
Code:
/var/log/messages gives:
Feb 8 16:22:45 norman-HP-G56-Notebook-PC kernel: [ 236.140141] usb 5-1: new full speed USB device using ohci_hcd and address 2[code]....
but if ds2490 module is loaded it works when run sudo.It seems from this that it is a lack of permissions to USB but I have tried all the methods on at http://owfs.org/index.php?page=udev etc. to overcome this and a few others but none work.I am running Ubuntu 10.10 kernel 2.6.35-22-generic #33-Ubuntu SMP

when I try to su, with the right password I know it is because I have reset it with a sudo, it says su: incorrect password. Looking at /var/log/messages I see su: Unable to open admin password file: Permission denied. This must mean that the file has incorrect permissions and or owner/group. I am wondering if anyone knew where the file was located and the correct permissions/owner/group.

Im having a serious issue with booting ubuntu 10.04, the issue being it wont boot up at all, after working so well for so long (i suspect some recent dodgy system updates are responsible) so I decided to just reinstall ubuntu from scratch again but wanted to retrieve some important files from my root device. So I am running the live desktop and I can see my previous filesystems under places but cannot mount or open my original root device where the files I want to recover are located, I receive this error msg:"Unable to mount 77 GB Filesystem.

I have a system running with few users and servers (apache/mysql/postfix). After extracting one tar archive in '/home' none of my users are being able to access their home directory. Even other system users (like www-data/mysql) are also not being able to access any directory. Only root can access the system. I have checked file permissions, many files/directories are set to 777 rest are 755.

I cannot install Kubuntu (or Unbuntu) 10.4 on my husband's computer. I have spent 5 hours on this and cannot get anywhere. I am deeply frustrated. The iso I burned to CD is good (works on 2 other computers). His computer will not boot from USB, no matter what I do to the drive order in BIOS. After loading the blue screen with the Kubuntu logo on it (and the blue-white dots), the screen changes to black and shows the following text:
BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built-in shell (ash) (initrafs) Unable to find a medium containing a live file system.
He really needs to get rid of WinXP. Kubuntu is what I have on my computer (and love it!). Here is some info about his computer:
OS Name Microsoft Windows XP Home Edition
Version 5.1.2600 Service Pack 3 Build 2600
OS Manufacturer Microsoft Corporation

I switch on the PC and it loads the Grub splash screen. However, it does not automatically boot the top entry after two seconds as it's supposed to and just hangs. I hit enter to boot it and it attempts to but after a few seconds gives me the error "unable to mount file system....a maintenance shell will be started"
This occurred after I was using it and then everything suddenly froze up on me and I had to crash out Now this!

I work for a company that makes portable devices running Linux and I was recently asked to make the underlying file system read-only for "security" purposes. Since the distribution is based on LinuxFromScratch, I know that very little writing happens at run time. So, even if the device runs on a usb flash device, I doubt that putting the root file system RO will be that beneficial. I am actually more concerned about a process actually breaking because it cannot open a file in RW mode than a process going rogue and filling the root file system with log files, etc. I'd really like to ear what kind of advantages disadvantages there really is with read-only file-systems.

How can you give total access to the system to a user other than root?
* Make the user a member of the root group.
* Change the UID of the user to 0.
* Add the user to the /etc/sudoers file.
I think none of these are correct answers.

I try to install my printer again after reinstall ubuntu 9.04. ("downgraded from 9.10"). Instead of asking for the local-user-login password, as it does for other system changes, it asks for a root password that I never had. What happened? How can I set this right?I made a printscreen.

I would like to know if it is possible to deny the access to a file for root? Would ACL's be a possibility? I have "googled" around but haven't found anything interesting (except SELinux). I should secure a password file to an important database.

Can't log into my XFCE desktop like I normaly do. all the sudden I get notified that my xsession lasted less then 10 secondsLooking at the error I can see this:
Unable to access file /home/username/.iceauthority: No such file or directory
Using failsafe I can start a terminal. From terminal I tried to start X
Code: sudo startx Result: Running on desplay:0
So I tried to run this;
Code: sudo startxfce4 And I get up a graphical desktop.
So this is not a critical situation as I easily can use this method to log on, but as there has been something causing this I would like to be able to resolve this nonetheless. Btw it is not the old chmod trick in play here, cause my .iceauthority file is gone alltogheter.

Whenever I try to do anything that requires administrative permissions, including Synaptic, the Update Manager, or installing something on the Software Center, the "Starting Administrative Application" task comes up on the window list, but then the window does not come up and whatever action was supposed to be taken does not happen; no error messages, nothing. Also, whenever I use su or sudo in the command prompt, nothing shows up when I type my password; then when I hit Enter, it gives me an authentication error.
EDIT: It seems that the "Add/Remove Applications" program as well as the Software center do not have this problem. Synaptic and the Updates Manager, however, still do not work.

I'm dual booting XP and UNR and I want to give users access to the windows file-systems but not to admin of Ubuntu.
At present I have given them a Desktop user account but that doesn't allow access to the XP file-systems. The only way I can see to enable that is to go to Advanced User Setting and allow them to Administer the System - which I don't want to do.

I have been using Ubuntu 9.10 Desktop version for around 1 month then i stoped using after installing windows 7, as I knew that there were the 10.04 version coming. So when it was released i went to torrent download the file and burned it on a cd. After that i insert the cd and use the wubi installer in there as i want to install them side by side. so after installing ubuntu i restarted the system and got into it. After a few minutes it appeared this error message "Not root file system is defined. Please correct this from the partitioning menu." So i was expecting it to be downloading problems. I went on to ubuntu website requested for a CD and it came today. So i inserted the cd did the same thing again.

Is it possible to run fsck on the root file system?
My Ubuntu 10.04 seems to be checking it's fs at boot...
It shows that the file system is in use and can get severely damaged!
Or the only possibility is to run it from a live CD?

My current installation setup has a separate partition for /, /boot, /home, /tmp, /usr, and /var. The problem I have is the root partition / is 98% full (4.3GB full). Cleaning temp files and log files won't help since they are on their own partition (and clean). I've removed all but two linux-images. Linux images seem to run at a size of roughly 105M. My root partition is 4.6GB. I can't seem to find any other options for cleaning up space on this partition. I have no idea what is taking up 4.6GB of space.
Disk Usage Analyzer has not been helpful since I have not been able to reconcile 4.6GB of memory with what it claims the total size of the remaining directories occupy. I've tried localepurge, gtkorphan, apt-get clean, apt-get autoclean, apt-get autoremove. I've removed all packages listed under Status -> Not Installed in the package manager. My root file system is still 98% full (4.3GB full).

Classic partition problem apparently. What do I do? the 11.04 wubi doesn't give a lot of installation options, so i just selected C drive, and gave it 10GB of space. instilled it, and when it goes to the desktop menu, that pop up appears saying No root file system is defined. Please correct this from the partitioning menu
In dual booting with XP. what do I do?

I plugged in my USb drive into my computer yesterday and tried to delete a folder. I was unable to do so and got the following message
Cannot move file to trash, do you want to delete immediately? The file "my file" cannot be moved to the trash. Show Details Unable to create trashing info file: Read-only file system
So when I click on delete I get another error message:
Error while deleting.
There was an error deleting Case Study Database. Show Details Error removing file: Read-only file system
At this point I can only click on Skip, Skip All, or Cancel.
I have not changed anything on the stick recently so I dont know what is causing the problem.

After freshly installing Lucid Lynx and tinkering for some time to get everything just how I like it, I managed to somehow remove myself and all other users from all groups. Now, obviously, I've restarted and I don't have root privileges as I am no longer a member of admin group. So I am somewhat stuck. I've looked at this page: [URL]. But annoyingly, there is no grub menu appearing on boot up (unlike previous Ubuntu versions). So I'm appealing for your help to either:
a) Show me how I can bring up the grub menu so I can access ubuntu in safe mode
b) Show me another way of accessing the system with root privileges. (Would using chroot from the Live CD work? I just thought of that now so I'll try it).
