Ubuntu Servers :: Upgrading Kernel Without Reboot
Dec 16, 2010
I have an Ubuntu 8.04 server running 2.6.24-23-server. I have a godaddy account and I am trying to upgrade my os version to 10.04, which requires a kernel upgrade. I have tried ksplice but kernel 2.6.24-23-server is not supported. I have heard about screen sessions but I have not found it possible to reboot one screen while having the other screen stay persistent if it is possible.So the main question is how to update Ubunut 8.04 to Ubuntu 10.04 with out rebooting the entire server? Rebooting is completely not an option at the moment.

I have one machine where I have several versions installed on different partitions. The base partition (/dev/hda1) is Slack 12.1. On a spare partition (/dev/hdc4) I had installed Slackware64-current. Last week I slackpkg upgraded and installed the 2.6.32.2 kernel, and now that partition will not boot. I know that with the new kernels the hd* designation has been removed, and have already redone that fstab (accessing it from a different boot) to reflect the sd*. Here is the slack64 section of my lilo.conf:
Code:
# Linux bootable partition config begins
image = /other/spare4/boot/vmlinuz

The server runs# uname -r2.6.18-128.4.1.el5However, today I executed yum update kernel*due to security advisory. I was just about to reboot the system when I realized that it runs VMWare Server Instance that will most likely fail to restart after kernel upgrade (I had a hard time fixing it after previous kernel update). Now I want to keep 2.6.18-128.4.1.el5 after reboot.I see that new kernel is scheduled for booting:
# cat /etc/grub.conf
default=0
timeout=20
[code]....

I'd like to install the 2.6.35 kernel while keeping Lucid (just not in the mood right now to get used to a new release). Can someone point me to a tutorial on how to go about this?

As seen in the screenshot, my update manager won't let me mark the proposed kernel updates for installation.I have heard that I would be able to mark them after a few days have passed ( I don't know the reason, though). Well, now it's been 3 weeks that I have them as "proposed updates" and I still can't mark them.I decided to run apt-get upgrade in the terminal and here is the output:
Code:
~$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done

I am building a live-cd using live-helper on Karmic (9.10). The process executes fine and I am able to build a live cd of ~200MB in size with minimal and xfce. But things does not work if I try to upgrade the kernel with the one of them from [URL] site. Ubuntu kernel team publishes the kernel for testing and I would like to upgrade the kernel for testing. But when I upgrade the kernel from inside the live-helper's interactive shell, it upgrades fine and iso gets created. While booting, it loads the kernel and errors out with the following message:
Code:
(initramfs) mount: mounting aufs on /root failed: No such device.
aufs mount failed.
I am running initramfs after installing the new kernel (a .deb file) using dpkg.
What else should I need to do for getting this to work?

I upgraded my Ubuntu 11.04 laptop to kernel 3.0.1 and when I try to start Conky using my custom conkyrc, the conky process dies. I played around with it and discovered (through trial and error testing) that the code for the CPU temperature crashes conky. It worked before the upgrade. how I can get the CPU temp monitoring working again in kernel 3.0.1? Here is the code that is crashing conky:

When upgrading kernel via RPM, do I just need to download the RPM, and then do:
rpm -ivh file.rpm ?
Is kernel-headers needed?
Do I want to use force on either?
Example:
# wget ftp://ftp.pbone.net/mirror/ftp.cento...1.el5.i686.rpm
# rpm -ivh kernel-2.6.18-238.12.1.el5.i686.rpm

Wow -everything works with alpha-3 version with a fresh install. Sound, wireless modem, processor speed scaling, sound controls, touch pad, all cores running,power management, battery, fans, etc. NVidia driver is also working. I tried multiple other distro installs - opensuse, Fedora, and ubuntu 10.04 - none worked. Also tried upgrading from 10.04 to 10.10 which didn't work either. also tried upgrading to 2.6.35 kernel which didn't work either.
I'm running a toshiba satellite a505-6030 with an i7 core, nvidia graphics gforce 310M. i didn't have to pass any arguments to grub either . First boot seemed to stall, rebooted machine, and it's been working perfectly since.

I'd like to upgrade the kernel in the ISO of a Ubuntu 9.10-based CD with proprietary applications, burn a new CD with this modified ISO, boot up with it, upgrade + add + remove modules and applications, and finally save the running system into a new ISO file which would now have the latest and greatest.
I have a couple of questions: 1. How can I download the kernel manually? Where can I find the latest vmlinuz + initrd files for Ubuntu 9.10?
2. Is it just a matter of replacing those two files, or are there other dependencies I should update in the rest of the ISO, eg. isolinuxisolinux.cfg: Change initrd.gz to initrd.lz, etc.?

I haven't used Linux very much, so I'm not sure how to do this. I'm presently running the 2.6.24-26 version of the Linux kernel on Ubuntu. However, I need to upgrade to 2.6.32. I have the source files (arch, block, firmware, drivers, kernel, include, etc), but I have no idea how to change the source of the kernel, or if there's an easier/automatic way to do this, and I specifically need the 2.6.32 version.

My old laptop has a broken screen. I tried using an external flat screen and win-xp would not run this screen. This is how I came to learn about Ubuntu. I loaded Ubuntu 9.4 and the computer worked with the external screen. The only problem was that during the boot process the (kernel text?) the white text on black screen over ran the edges of the external screen. Once the Ubuntu was loaded the window fit the screen perfect. Now my new problem. After a year of perfect use, the battery ran down and the computer shut itself off.
When I put the charger back on and rebooted the laptop, the ubuntu partly opens then hangs up on the kernal (white text on black screen) because of the screen overrun problem I can not read the text. I can boot still boot from the 9.4 CD. Is there anyway I can correct the problem by re-installing 9.4 but not wiping out my person data and files. In other words is there any way to repair the O/s that is defective, without losing my work?

I've never compiled a kernel before and I'm in need of the 2.6.28 kernel (two words: macbook aluminium).
I guess my biggest question is, will this guide work well for F10? I would hate to get half-way through it just to find out that F10 does something different than F08 or F09. Is there anything that you experts can see right away that would possibly be disastrous? If things do come to worse, I can simply select the previous kernel at GRUB boot right?
Or will the Fedora team be releasing the update soon through the package manager? Is there a way I can activate the development version and only get the kernel update?

I upgraded, using package manager, to the latest kernel (2.6.35.10-72); I upgraded also kmod-nvidia and kmod-wl to the latest version, and the upgrade worked.After restarting the PC, though, it wouldn't boot Fedora: it stops at:"setting hostname for <my laptop's name>:[OK]"then it simply hangs there. It doesn't move, it doesn't boot, it doesn't ask for a login and it doesn't let me use command line.I can, however, boot and run Fedora fine if I select the previous kernel from the GRUB menu.Anybody can give me a hint to find the cause of the problem?

Was upgrading to the newest kernel in RHEL5 from 2.6.18-164 to 2.6.18-164.10.1 but when I rebooted the machine it gave me these errors.
Unable to access resume device(/dev/VolGroup00/LogVol01)
mount: could not find filesystem /dev/root
setuproot: moving /dev failed: no such file or directory
setuproot: error mounting /proc no such file or directory
setuproot: error mounting /sys no such file or directory
switchroot: mount failed: no such file or directory
kenel panic - not syncing Attempted to kill init!
So I rebooted the machine and picked the old kernel to boot up (2.6.18-164) and everything came back up fine. I don't understand why it keeps failing when trying to boot to the new kernel. I am using the yum upgrade command, is there a different command I should be using?

Code:
1. Upgrade the kernel and kernel-modules packages normally.
That sounds simple except that day-to-day, I don't run a stock Slackware kernel. I compile and run my own and always have. As I look back on my history with Slackware, I don't think I've ever upgraded kernel packages once I got a system up and running. When there's been big changes (2.4 to 2.6, for example), I've done a full re-install.
Most recently when I made the jump to 64bit, I did a full install using the huge.s kernel and once everything worked, I downloaded the current source from kernel.org and was on my way. I haven't booted huge.s since that day.
I do, of course, know how to upgrade my own custom kernel, but I like having huge.s installed as a backup. If I upgrade gcc/glibc, compile a new custom kernel and update lilo.conf/fstab without upgrading huge.s, then I will be left with only one working kernel.
So, my question is: is it simply a matter of running upgradepkg on the 6 kernel packages (headers, modules, firmware, generic, huge and source)? or is there more to it than that..ie, what about the system maps and symlinks in /boot?

I have a hand-built kernel in Lenny. It's much smaller and faster than the stock kernel and doesn't need an initrd, but I am not sure how to upgrade it in a way that will be compatible with the new udev package. The recommended procedure is to upgrade the kernel and udev together and then reboot before doing the rest of the upgrade, but obviously I can't do that.
There seem to be two possible procedures I could follow:
1) Upgrade kernel sources and rebuild and install the kernel, then reboot and upgrade udev. But then the new kernel would be booting with the old udev and I don't know if that would work.
2) Upgrade, rebuild and install the kernel, then upgrade udev without rebooting, ignoring the warning messages. Finally reboot into the new kernel.

I use Debian Stretch (testing). After upgrading to kernel 4.4 the system doesn't see my main soundcard at all -- so, no sound. And now I also get this message every boot:

I have a Thinkpad which uses a Realtek Wifi controller. I read that with the 2.6.32 kernel, the driver is now part of the kernel by default. I have pardus 2009.2 installed and would like to upgrade the kernel from 2.6.31 to 2.6.32 But i cant find this kernel in the default repositories.

I have several remotely hosted boxes (running 9.10 Server 64-bit) that I'd like to upgrade at some point to Lucid Server, preferably using do-release-upgrade.
Is this possible currently via SSH, without lockout or breakage?
Theoretically, I can have the datacenter staff do the upgrade for me, but I'd prefer to do it myself if it's possible to do so.

We have an Old 7.10 server which i want to upgrade to 10 but i cant work out how to do it, or if its still possible. I ran this:
sudo apt-get install update-manager-core (Which says its up to date)
and then
sudo do-release-upgrade
which i found here:
[URL]
But all it comes back with is:
No new release found.
From what i gather i need to go to 8 before i can go to 10.

after upgrading to lucid lynx ubuntu doesn't boot with the new kernels 2.6.32-22-generic and 2.6.32-23-generic (also in recovery mode). But it's does boot with the previous 2.6.31-21-generic kernel. At the time i was hoping to wait it out, but a new kernel has come and the problem persisted. I've been trying to find a solution for this but somehow, amid lots of failed boot blank black screen threads, i didn't relate to any solution. The boot seems to go well until a pixelated logo appears (before the login screen), then goes to a blank black screen and there it stays stuck with no remedy. Looking into dmesg logs - albeit some differences between 2.6.31-21 and the newer 2.6.32-23 - the failed boot seems proper in both logs. In Xorg logs the differences are bigger but i cannot pinpoint a source for this problem.

I recently decided to venture into the world of Linux/GNU by installing Ubuntu.
Before installing, I had a 190gb partition for windows 7 and 45gb of unallocated space. Through Wubi, I used the advanced partition editor to make a 6gb swap partition and a 22gb root partition for Ubuntu. All went well, but when I rebooted, I was unable to choose linux.
I installed Ubuntu by using Unetbootin to put the Ubuntu ISO on my USB drive. After installing, I disconnected the USB drive, and I was unable to choose the linux kernel option on the GRUB menu. When I do, my system just restarts and presents me with the GRUB menu again. However, windows 7 boots up perfectly.
I'm assuming that GRUB is somehow trying to boot the linux kernel from the USB. How do I change it to boot from the installation I made on my harddrive?

Can I use the config for my current kernel (the jessie 3.16 one), and use it to build a more recent kernel (3.18)? Do I just copy across the config and try and build with it, or is there some tool that will bring across the existing config but also set up reasonable defaults for any new options in the newer kernel, and any other migrations that might need to be applied?
