Ubuntu Installation :: Kernel Upgrade To 2.6.32-23-generic Broke My LVM - RAID And GRUB

Jul 4, 2010

I recently updated the kernel to the newest version(2.6.32-23-generic) using the update manager and now I am unable to boot in to my Lucid installation.

My setup is LVM on top of a RAID 0 array. My computer had been running in this configuration since Lucid was released.

The Error Code I get on Boot is to the effect of: /dev/mapper/ubuntu-os is not available.. and then I get kicked in to Busy Box.

Once in Busy Box if I try to use mdadm to mount the RAID array I get this error:

If I boot in to the live CD I can mount all of the partitions and LVM volumes, so it does not appear to be a failed drive or volume.

I have looked in the mdadm.conf, lvm config and grub config files and searched the "Google" for an answer with no-avail...

Ultimately I would like to find a solution which doesn't involve a re-installation.

Ubuntu Installation :: Unable To Use Nvidia With Kernel Upgrade To 2.6.32-23-generic

Jun 30, 2010

Upgraded to latest kernel 2.6.32-23. Ubuntu 10.04 I run a twinview video configuration of 2 screens @ 1920x1200. On booting, X wanted to go to low res for the session, which reverted to one screen (that is, I lost the twin view), but actually kept the 1920x1200 res on the one. I restarted X on got both screen working with the second as a replica of the first. Something has changed in this version of the kernel. Reverted to the previous Kernel version (22) and all is sweet (twin view is back working). But this can only be a temporary workaround.

Ubuntu Installation :: Kernel Upgrade To 2.6.32-23-generic-pae Breaks Fglrx

Jun 30, 2010

I have an ATI radeon HD 3400 series video card, and the open-source drivers make my computer run really hot. I tried installing FGLRX by using "Check For New Hardware Drivers", but it did not work, so I installed the ATI catalyst 10.5 package from AMD's website, and am using Xserver-xorg-core-1.7.6-2ubuntu7+backclear1 from k0ekk0ek's PPA so there is no lag when minimizing windows and such.

Everything was perfect until the 2.6.32-23 kernel update came along. I let it update, and rebooted, but the ATI driver no longer starts, even when I uninstall and reinstall it.

I am just using the 2.6.32-22 kernel for now, as the 2.6.32-23 kernel still runs hot without the ATI driver enabled. I would like to start using the new kernel at some point...

Ubuntu Installation :: Grub Broke After Wubi Upgrade / Sort It?

Aug 18, 2010

I beleive I had version 9.x installed. I upgraded once and everything was fine. I went the upgrade manager again and it found some more upgrades. The upgrade messed with grub. It then told me there were no new upgrades. Then I rebooted and it says

Try (hd0,0): NTFS5

Then the screen clears and there is some text I can't read and then it says command not found. Then it reboots.

Is there a way to fix this?
If not is there a way to recover the files from the disk image file.

Slackware :: Software RAID 1 Versus LILO / Kernel-generic - ERROR: No /sbin/init Found On Rootdev

Jul 1, 2011

I'm currently trying to setup Slackware 13.7 on a server, using software RAID 1. I'm using the README_RAID.TXT document at the root of the Slackware disc as a reference. Anyway, here's what I have so far.

/dev/md1 -> /boot partition
/dev/md2 -> swap partition
/dev/md3 -> / partition


[root@raymonde:~] # fdisk -l /dev/sd{a,b}
Disk /dev/sda: 41.1 GB, 41110142976 bytes
255 heads, 63 sectors/track, 4998 cylinders, total 80293248 sectors
Units = sectors of 1 * 512 = 512 bytes


I created an initrd image using mkinitrd -F, added an according stanza to /etc/lilo.conf and ran 'lilo' after that. Now I can boot on the vanilla huge kernel all right. But I can't seem to boot on the generic kernel. Whenever I try to do this, the boot process stops short on the following error message:


mount: mounting /dev/md3 on /mnt failed: Device or resource busy
ERROR: no /sbin/init found on rootdev

Ubuntu :: Broke WiFi By Kernel Upgrade / What To Do?

Jan 13, 2010

I'm running Ultimate Edition 2.4 on an Acer Aspire 3500 lappy, yesterday I allowed my system to upgrade the kernel (from 9.10 kernel 2.6.31-17 to 2.6.31-18 generic) as per usual but when it rebooted I had no WiFi. The network manager didn't even have a wireless section, only wired, and I couldn't setup a wireless network either. If I reboot into the earlier 2.6.31-17 kernel everything is OK.
Another problem is that even tho I have no screensaver enabled and no power saving options enabled, (ie screen never disabled) after a short time of no use the screen goes blank. If within a few minutes I touch the pad or hit a key the screen returns but if it's been an hour or so nothing I do will wake it up,even tho there is still disk activity etc, and the only way to recover is with a hard reset, hold power key to reboot.

Slackware :: How To Modify Grub To Boot Using Generic Kernel

Feb 16, 2011

My Slackware boots using the huge kernel. I am not using LILO; I am using GRUB from the extras directory on the DVD. I followed the tutorial @ [URL] up to the point where it discusses modifying LILO. My /boot/grub/menu.lst reads, in part:

# Linux bootable partition config begins
title Slackware Linux on (/dev/sda7)
root (hd0,6)
kernel /boot/vmlinuz root=/dev/sda7 ro vga=normal
# Linux bootable partition config ends

This boots the huge kernel. What changes must I make to the above menu.lst entry to boot using the generic kernel?

Debian :: Squeeze Kernel Upgrade Broke Suspend To Ram

Dec 12, 2014

Yesterday, I ran a security update that upgraded my Squeeze kernel from 2.6.32-48squeeze8 to 2.6.32-48squeeze9.

Ever since then, my suspend to ram (STR) function is broken.

The machine will suspend normally, but will not resume. When I try to awaken the machine, I can hear the fan in the tower start up (the subject machine is a desktop computer, please see below for specifics), but the machine seems to be otherwise dead (e.g. the monitor stays blank, pressing the "caps lock" key on my keyboard does not activate said keyboard's "caps lock" led, Ctrl-Alt-F[x] has no effect, etc). My only recourse at that point is a hardware reset (ouch!).

I tried running Code: Select allpm-suspend from a terminal, with no joy. Same result running Code: Select allecho -n "mem" > /sys/power/state from a terminal.

I checked the /var/log/pm-suspend.log file and noticed that each Code: Select all...performing suspend line used to (before said kernel upgrade) be directly followed by a Code: Select all...Awake. line, but, now, all said Code: Select all...performing suspend lines are followed by an Code: Select allInitial commandline parameters... line.

Before this, STR has worked well ever since I first loaded Squeeze on this machine back in 2012.

Code: Select allSqueeze 6.0.10; 2.6.32-5-amd64

Intel i7-980 Gulftown CPU
Asus P6X58D Premium Motherboard
EVGA GeForce GTS-450 Graphics Card

Ubuntu Installation :: 11.04 Onto Spare HD, Broke Win7 On Raid?

May 3, 2011

I have a dell with win7 installed on two disks as raid0. I added a 3rd HD and installed 11.04 on to it. This boots ok but only Linux shows in the grub menu. Win7 is not there and I have no way to boot it as the installer put grub on disk0 of the raid overwriting the windows boot prog.

Ubuntu Installation :: Old Kernel In Grub After 9.10-10.04 LTS Upgrade

May 12, 2010

I performed an upgrade via the Update Manager from 9.10 to 10.04 LTS and it seemed to go flawlessly. However, now I cannot seem to be able to remove the old Kernel from 9.10 in the package manager. It does not even show 2.6.32-21 as installed but it still shows the old Kernel in Grub. I did a sudo update-grub but it was to no avail.

Debian :: Installation Broke Raid Setup?

May 27, 2011

My system includes two 120GB disks in fake raid-0 setup. Windows vista is installed on these.For Debian I bought a new 1 TB disk. My mission was to test Debian and I installed it to the new disk. The idea was to remove the disk afterwards and use windows as it was before. Everything went fine. Debian worked perfectly but when I removed the 1 TB disk from system grub will show up in boot in grub recovery mode.

Is my RAID setup now corrupted? Grub seems to be installed on the other raid disk? Did grub overwrite some raid metadata? Is there any way to recover the raid setup?

dmraid -ay:
/dev/sdc: "pdc" and "nvidia" formats discovered (using nvidia)!

Ubuntu Installation :: 10.10 Always Boots Kernel

Jan 9, 2011

I just noticed I'm not running with the latest kernel.

This box was originally installed as Ubuntu 10.04, then upgraded to 10.10.

I just recently noticed that, even though kernel 2.6.35-24-generic is installed, this box seems to insist on booting up with 2.6.32-24-generic.

Looking at /boot/menu.lst, it looks ok. (default is 0, and first kernel in list is 2.6.35-24. 2.5.32-24 is the *last* one in the list!)

Ubuntu Installation :: 17 - 14-generic On GRUB - Only 14 - Works

Jan 27, 2010

I've played about with Live CD's and sort of got it working on a PS3, but that's about it. Now, my problem.

Basically, what happened is that I installed Ubuntu 9.10, and then I installed whatever updates it wanted, and then ...17-generic pops up, but doesn't do anything other than load up a terminal type thing full screen.

Here's everything GRUB says.


I'm pretty sure it's supposed to be part of the updates I did, but to be completely honest I'm not even slightly certain.

I don't know if there's any more info you'd need from me about my computer, but if there is could you tell me how to find it.

So the questions I'm asking really: Is meant to be an updated version? and if so, How do I make it do what it's meant to do?

After installing Ubuntu my Windows XP BSOD's on startup. I have posted in a Windows forum, but they seem to be terrified that I've used the word "Ubuntu" or maybe I'm being plain impatient. Do you know of anywhere which specialises in dual-boot problems or something? Thanks again

Ubuntu Installation :: Why Would Generic Kernel Be Installed From Server 9.10 Cd?

Jun 4, 2010

I installed Ubutnu 9.10 Server on my Dell Server for LAMP & OpenSSH server. After the install was complete, I noticed the the kernel installed on the server was 2.26.31-14-generic instead of 2.26.31-14-server.I am wondering why would generic kernel be installed from ubuntu-server 9.10 cd? And how do go about chaning to server kernel? Or do I even need to do that? Would generic kernel work as server kernel ?

Ubuntu Installation :: 2.6.31-19 Upgrade Broke Grub2

Feb 7, 2010

I upgraded yesterday ubuntu 9.10 to 2.6.31-19 kernel. After reboot, I get stack to GRUB black screen. No possibilities.

My set-up is triple boot 9.04, 9.10 and winxp. The MBR is handled by win boot.ini with no problems. Each ubuntu partition has a grub installed in it.

9.04 is on sda5 with grub installed on it ext3
9.10 is on sda9 with grub2 installed on it ext4

I am able to boot into sda9, via grub of sda5 obviously passing the correct kernel parameters and UUID.

Ubuntu Installation :: Upgrade Broke Web Browsers?

Apr 10, 2010

I upgraded to 9.1 and now my web browsers are not working properly--FireFox would not connect to certain sites, others worked fine. I installed Chrome and it worked for a short period--now none of my browsers work at all and package install manager does not work. Overall performance is much slower than before upgrade--boot time is about 4 times slower. I'd like to fix this build because I had it tweaked just the way I liked it before the upgrade--it was working great and now I'm sorry I upgraded there any hope or should I just start with a fresh install of 9.1 or even the previous version

Ubuntu Installation :: Latest Upgrade Broke Booting?

Mar 17, 2010

I just did the latest upgrade in 9.10 via the update manager and it required a reboot. When I rebooted Ubuntu failed to load. In recovery mode it fails saying that it can't find my root device and has some suggestions about what might be wrong. I looked at the file it listed in /proc/something and the devices available by uuid in /dev/ and what's listed in /proc/something isn't in dev. I haven't made any changes yet for fear of causing worse damage. The shell it bumps to is ASH and it doesn't look to have much editor support to make changes to the proc file(ECHO > ?). Is there a safer way to get my system back online?

I'm running 9.10 AMD64 on a Dell Inspiron laptop with a dual boot to Windows 7 (For browser testing web apps/sites)

Ubuntu Installation :: Lucid Upgrade Broke Login?

Jun 23, 2010

I had a working workstation with Karmic. Then I decided to upgrade to Lucid. Bad move, it turns out.First the upgrade crashed. Just stopped doing something for hours on end, and I eventually had to reboot. After that, I had to apply lots of apt-get and dpkg love to get the machine to book. Now, I *think* I have a Lucid system, at last. Only that it doesn't work where the Karmic system used to...Our setup uses kerberos and autofs. To begin with, the upgrade lost my /etc/krb5.keytab (making it impossible to log in), but that can be easily replaced.Now, I can log in, but my home directory doesn't get mounted. In /var/log/auth.log, I get this:

Jun 23 11:13:58 pc13477 gdm-session-worker[1801]: pam_krb5(gdm:auth): pam_sm_authenticate: entry (0x0)

Ubuntu Installation :: Libpango Upgrade Broke Synaptic?

Mar 4, 2011

I ran a system upgrade today and it froze at "unpacking replacement libpango1-common". It just wouldn't go on. The upgrade kept on showing "unpacking replacement ..", the process used zero CPU time, so I killed it, removed the lock and after Synaptic asked me to, I ran sudo dpkg --configure -a. Now I can't install anything. Everytime I try to, I get an error telling me I should run "sudo apt-get -f install", however, whenever I do that, another endless installation of libpango1.0-common starts. I tried various things like installing that package manually, removing it and so on, but nothing helped. Any advice on how to get my package installation system working again is warmly welcome.

Ubuntu Installation :: Lucid Upgrade Broke Monitor Setup?

May 2, 2010

Upon upgrading from Karmic to Lucid, Everything comes up, seemingly fine. Once logged in to the OS, my three monitors show the desktop wallpaper as well as all the icons on the desktop. A few programs that I have set to autostart do so.

However for some reason, I can only access one of the three monitors. (And not the one with the gnome-panel.) As soon as I drag my mouse from my third monitor onto the one next to it, I loose complete control of it, and it starts dancing all over the place. If I try to drag a window from one screen to the next (using Alt-Left CLick + drag and not moving the mouse onto the other monitor), the the app goes from one side of the working monitor to the other side (like it's wrapping around). Though I can see it on the other monitor for a little bit until I get it far enough for it to wrap.

Here is my xorg.conf:


Section "Files"
FontPath "/usr/share/fonts/X11/misc"
FontPath "/usr/share/fonts/X11/100dpi/:unscaled"
FontPath "/usr/share/fonts/X11/75dpi/:unscaled"

Ubuntu Installation :: Firefox Flash Plugin Broke After Upgrade To 10.04?

May 25, 2010

I had the Adobe flash plugin working under 09.10 in Firefox; now after the upgrade to 10.04, it doesn't work.When I go to a web page with flash video, I get the message "Some plugins are not installed" and video will not display. I click on the button to install the plugins and select Adobe Flash. I get the message "Package is already installed." I go back to the web page and the same thing happens again.In Ubuntu Software Center I see that package restricted-extras is installed.

I tried going through Tools / Add-ons in Firefox, but the list of add-ons wouldn't load at all that way.I also tried going to Adobe's web site, but for versions of Ubuntu 09 and later it offers an "APT" file instead of a .deb. Firefox asks what application to use to open an "APT" file and I don't know what to tell it... I'd be fine downloading a .deb or using apt-get or Ubuntu Software Center though.

Ubuntu Installation :: Upgrade From 10.04 To 10.10b Crashed With GError, Broke System

Oct 17, 2010

i wanted to upgrade my ubuntu system to meerkat beta via update manager like i upgraded it the last 5+ times.

a bug showed up that i can recall from updating files previously: some software installtions via update manager triggered the programm nicotine+ (i think is was something like man-lib or man-db that, when called by the installtion programm, would trigger nicotine too). since i can close that nicotine+-window and the installation process isnt bothered any further i didnt mind.

now with this upgrade, i had to close nicotine+ around 5 times since it got triggered together with some of the files that got updated/installed in this upgrade.

and then what happened: GError something about an "unrecognized image file", it concerned a py file that was named "nicotine"...

so i waited for 10 mins and figured out that the update process had stopped. i couldnt resist and logged out, wanting to delete nicotine from my system and to reinitialize the upgrade. well, nothing works since then, grub only lets me choose different kernels which didnt help much as there was no way to startx.

my question is:

how can i reset this upgrade mess or bring this pending upgrade to an end? can i do an upgrade via network, based on the emergency shell that comes up in some kernel-recoverymodes? or should i burn a livecd, boot it and then do what? repair? try another upgrade? delete nicotine?

having 'consumed' ubuntu for years now i still wouldnt know what else to do then posting here.
