Ubuntu Installation :: Cannot Boot After Update - Udevadm - And No Chroot Command
Dec 20, 2010
I installed Ubuntu Netbook Edition 10.10 on my Eee PC 901 (the one that has 2 SSD's). It all went fine, and I ran the update manager straight after install and config. It installed the updates (all 198 of them!) without error. I was prompted to restart, so I did. I got the error "udevadm trigger is not permitted while udev is unconfigured". I found out that this error is well documented, and I followed the guide at [url](apparently it affects all variants, not just UNE).
It went O.K., until I tried the command "sudo chroot /media/newroot". I got the error that "cannot run command '/bind/bash': no such file or directory". What should I do?
I cannot boot into and earlier kernel (problem/current one is 2.6.35-23-generic) I can only fix it via live USB stick.
I upgraded to the last ubuntu last week and since I get the error: "udevadm trigger is not permitted while udev is unconfigured."I followed different posts on the forums but none helped: [URL]I did the sequence:
"1. Boot liveCD 2. "sudo fdisk -l" to find your boot disk, in my case it is /dev/sda5. 3. "sudo mkdir /media/newroot"
I just performed an update thru the Update Manager, & on re-boot got this message: ( Ubuntu 10.04.1 LTS, kernel 2.6.32-24-386 ) udevadm trigger is not permitted while udev is unconfigured. Gave up waiting for root device. Common problems :
- Boot args ( cat /proc/cmdline ) - Check root delay= ( did the system wait long enough? ) - Check root= ( did the system wait for the right device? ) - missing modules ( cat /proc/modules; ls /dev )
ALERT! /dev/disk/by-uuid/df0200e3-e6e9-439a-922f-100d92af0c58 does not exist. Dropping to a shell!. BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) built in shell (ash) (initramfs)_ Info: I can boot into older version: Ubuntu 10.04.1 LTS, kernel 2.6.32-23-386. The Update Manager does not seem to want to show any updates that are available.
I recently updated, and now when I boot it only goes as far as grub command line. There is no grub menu. The computer is a Dell Inspiron 8600 laptop with only Ubuntu installed -- no dual boot, no weird partition schemes. Originally installed Ubuntu 09.04 on this computer, upgraded a couple times and it currently has (had) 10.04.1 LTS running. The update should have upgraded from kernel 2.6.32-23 to 2.6.32-24. I can boot with a live CD and mount the hard drive. The drive seems fine, so it appears to be simply a grub config issue. I have to boot with live cd to get online to check for potential solutions. So I'm taking some notes on how to use grub.
I am trying to install ubuntu 11.04 to my laptop, currently I have 10.10 installed and working. When I try to boot the computer from USB for installation, I get (after waiting a few minutes):
[Code]...
I am currently using windows 7 and ubuntu as dual boot. I didnt have this problem when I was installing 10.10. I am not sure but I think I upgraded my BIOS after my 10.10 installation, so that might be related. I didnt change anything else related to hardware since.
I am not sure what other information I should provide, Also note that given error message might not be 100% correct as I have typed it from a photo.
I use Parallels 5 for Mac (10.6.4). I started my Ubuntu 10.4 virtual machine and it didn't load the Ubuntu Gnome desktop. In stead I did get a command line prompt. I could login with normal username and password, rebooted again, but same result.I tried to update the system with code...
I was updating the security updates in my deskptop. It did not executed successfully even after 7 hours. It remain just like hang up. So I switched off the PC and rebooted. Then it is showing the error: "udevadm trigger is not permitted while udev is unconfigured. Gave up waiting for root device."
Now my Lucid Linx is almost dead. There is also no 'Repair' option while booting from Ubuntu 10.04 CD. Pl help to restore it.
In a script that I'm still writing, I'm trying to build a package from source within a chroot'ed environment. 1) I could chroot and then cd to /usr/src and then manually install the package. 2) I could chroot and then run the installation script from the proper directory. 3) What I want to do and what's giving me issues, is to issue a command similar to this:
Code: chroot /root/me/here cd /usr/src ...and have it do the installation after changing to /usr/src.
Recently did a clean install (instead of upgrade) of 11.04 from 10.10 and this error bugged me for the first time.
ubuntu@ubuntu:~$ sudo apt-get install grub-pc Reading package lists... Done Building dependency tree
[code]....
followed this one too to the letter: ubuntu@ubuntu:~$ sudo chroot /mnt/clean/sda1 apt-get install -y grub-pc chroot: failed to run command `apt-get': No such file or directory tried this one too:
ubuntu@ubuntu:~$ sudo grub-install /dev/sda1/usr/sbin/grub-probe: error: cannot stat `aufs'.and this too which got me a bash something:
ubuntu@ubuntu:~$ sudo mount /dev/sda1 /mnt ubuntu@ubuntu:~$ sudo mount -o bind /sys /mnt/sys ubuntu@ubuntu:~$ sudo mount -o bind /sys /mnt/sys
recently we decided to make our own panel (like Plesk or cPanel) but for Ubuntu and it will be licenced under GPL (like any other professional sofware).want to make a panel not only that fits our needs but also the needs of other system administrators and domain owners. We researched other panels and found out that non of them has security/look/ease of use in one package. Bad codig is another problem found in other panels.I made a short overwiev of what I think we have to have in the beginning.I Security :1. Completely chroot enviornoment where every single service is in chroot mode (bind,mysql, postfix, .... )2. Easily managed IPtables trough web-based interface. 3. Coding rules has to be strict.
II Software selection : 1. MTA - Postfix 2. POP - dovecot
I've run the command "sudo apt-get update" from terminal, showing no update to do.Then I've run the update manager (System-Administration-Update Manager) and it has shown an update (adobe flash).I thought that "apt-get update" command and update manager were the same... Why do I have different results ? Is something missing in my "sources.list" file ?
I've been searching the web, without finding any sollution to my problem.vsFTPd is acting really weird. I've never seen this problem before, and I've been using vsftpd for some years nowWell.. The thing is, I've made a user that chroots to the folder /var/www on my server. And when I then try to chmod the file /var/www/htdocs/testsite/index.html through my ftp-client, I only get the error "550 SITE CHMOD command failed.", and when I then check in my /var/log/vsftpd.log it says
Code: FAIL CHMOD: Client "192.168.50.58", "/htdocs/testsite/index.html 777" Which I think would mean that it tries to chmod the file "/htdocs/testsite/index.html" instead of chmod the
Ok so I have a USB external hard drive with Ubuntu 10.04 LTS on it but I did something to ruin it's grub or something. So what I did to make my USB HDD bootable again is:
I don't know what to do about that error. It took me a while to understand how to learn chroot and thanks to some ..... videos I finally learned how and then it felt like a climax when I was about to issue the update-grub command and then when it didn't work, I felt bad lol .
I made a live USB memory stick / pendrive with Ubuntu netbook remix 10.04 using my desktop computer. I want to install / update my netbook that has no network function yet. I booted the desktop with the pendrive & ran update manager. I want to update the kernel so I will have the driver that will operate my netbook ethernet.Acer AOD260 has Ethernet Controller: AR8151 v1.1 Fast Ethernet, Atheros Communications & Network Controller: Broadcom 4727 (rev 01)and will not work from the current release of 10.04 (too new) but there are supposed to be drivers in the newer kernels.
Running Update Manager I get a box labeled "Debconf on ubuntu" & says "Configuring grub-pc". There is an entry box that says "linux command line:" & is empty. When I press the help button I get the message "The following Linux command line was extracted from /etc/default/grub of the 'kopt' parameter in GRUB Legacy's menu.lst. Please verify that is correct, and modify it if necessary.The installer is hanging, Preconfiguring packages ..., probably waiting for a response, but I have no idea what to do.
I just tried to upgrade my server to the latest version of Bind9 and the process fails gets frozen.First note that I have Bind in a chroot jail.When I try the upgrade, or the recommended "dpkg --configure -a", it displays this then hangs:Quote:
Setting up bind9 (1:9.7.0.dfsg.P1-1ubuntu0.1) ... * Stopping domain name service... bind9 rndc: connection to remote host closed
Recently I messed up GRUB boot loader in my laptop installed with Ubuntu which resulted in grub rescue prompt. So I had to boot Ubuntu Live CD to get it fixed. Thought of blogging it, may be useful for some one.
This fix involves two steps. First one is to chroot into Ubuntu installation partition. Second one is to install the grub MBR (Master Boot Record). I am using Ubuntu Lucid 10.04 and Live CD also of same.
Problem occured yesterday and has added 3 mins to my boot time. all i can say about it is that it occured after a yum update and then a crash while using wine. i navigated to the file but really cant say much about it. however the pci call there makes me wonder if it is related to the post below.
I updated my lucid alpha testing (64 bit)install after which I am unable to boot into any of my Ubuntu installs(sda11 has a dedicated Burg partition and sda10 has the stable karmic (32 bit)install and sda9 has the testing lucid install) Now I am trying to recover (rewrite Burg or at least grub2 on the MBR) my installs
This is what happens custom@custom:~$ sudo mount /dev/sda10 /mnt custom@custom:~$ sudo mount -o bind /dev /mnt/dev custom@custom:~$ chroot/mnt
[code]....
i tried a slightly different code with little success
custom@custom:~$ sudo mount /dev/sda10 /mnt mount: /dev/sda10 already mounted or /mnt busy mount: according to mtab, /dev/sda10 is already mounted on /mnt
[code]....
I also ran a whereis for bash and it also is there
I'm having a bit of a nightmare with my ubuntu hardy server (using hardware raid 1+0). Following a power cut I get the message "udevadm trigger is not permitted while udev is unconfigured" on boot. Before the power cut the server had been up for ~450 days.
I managed to get access to /boot (which was empty) by using the repair option on the alternate cd and mounting /dev/myserver/root. I've installed the packages linux-headers-server, linux-image-server and linux-server. The various 2.6.24-29 files were installed and update-initramfs was automatically run (I noticed others have used update-initramfs to solve this error when upgrading from 8.04 to 10.04 in some posts I've read). No luck with this though - just the same error booting. I've also tried reinstalling udev, but again with no success.
I rebooted and pressed the Esc key to get the boot menu up. Only options were for kernel 2.6.24-26 (rather than the 2.6.24-29 just installed). I ran the recovery option anyway and got "/dev/mapper/myserver-root does not exist".
I updated from 10.04 to 10.10 this afternoon, and after a reboot, I can't start ubuntu in the new kernel. Grub shows up fine, but after selecting the new kernel, all disk activity stops after a while. When booting in safe mode, the same thing happens.
Oddly, booting in the old kernel does work. I'm not sure which log files might be of use here, so haven't gotten much further..
[edit] Just tried to boot in the livecd, doesn't work either, same problem.... I guess there is a driver problem somewhere most likely
jump straight in with a problem. I'm experiencing the same problem mentioned here; where it was suggested to start an individual thread.I have been using ubuntu as a dual boot with vista for a couple of months. Apart from a few hiccups I've been very pleased, but after an update I am unable to boot ubuntu. It appears to be the same issue in the link above.
I originally installed 10.4 (because my first attempt with 10.10 would not install (turned out to be duff CD)) and then updated to 10.10. All was fine until this latest automatic update.I've tried a few things suggested -- copying the c:ubuntuwinbootwubildr file over c:wubildr -- with no luck... I'm worried about making things worse and thought I'd ask first. I hope that's OK.I also tried working from my liveCD, but it only gave me the option to install (because it's 10.4 and I've updated?
I updated to 11.04, looked down after about an hour and a half, and my laptop was off. Now when I turn it on, it acts like it's checking my desk, but it says something like "/ is not available or doesn't exist press s to skip, or m to manually recover" then when you skip it's like "/mnt is not available" It could be possible I accidentally turned it off during the upgrade.
I recently installed Ubuntu 11.04 via wubi.exe to dual-boot between Ubuntu and Windows XP Home Edition. Ubuntu was the default OS to load on boot. I tried running a few updates in Ubuntu through the update manager, followed the instructions in the wizard, and restarted my computer when asked. The computer now automatically boots straight into the "GNU GRUB version 1.99~rc1-13ubuntu3 Minimum BASH-like line editing is supported..."
I have only just started to get into Linux. I have no idea how to get through this portion. I can't load back into Windows either (at least...I'm not sure how to. I never get the opportunity to choose which OS to launch). I've tried researching this issue, but still not having a lot of success. My only current option is to completely reformat my HD, but this is (hopefully) not going to be needed. If I could just get back into Windows I think I could probably reinstall with Wubi.
Yesterday I got installed Ubuntu 11.04. After I got updated with update manager everything was OK until I rebooted the system so that update can tack effect. When I rebooted It's stuck in the middle of something. (No GUI). I tried recovery mode but same thing. Then I tried Previous version and it worked fine. Now I can boot into system but each time I need to select previous version.
my brother's computer is pretty slow, but was working fine with ubuntu karmic, but I decided to finally upgrade him to lucid the other day, and recently his bootups take, at worst, 10 minutes,when in karmic it took way less. It just sits on a blank screen (not even a blinking cursor)
His pc's specs are: 1.4 Ghz processor (single core) on-board graphics (no graphics card) two hdd's one 80GB and one 150GB (the 150GB is split into 3 partitions) 465.7MB of ram 4.1GB of swap
I've attached his bootchart and it seems that Modprobe, Framebuffer, udevadm, and blkid are taking the most time to load, but I dont really know, i'm new to linux. Also how do i disable bootchart now that iv'e used it. p.s Heres he same bootchart just in case the one attached gets shrunk by ubuntuforums [URL]..
