Network Upgrade for Ubuntu Server From 8.10 to 9.04

How do I upgrade Ubuntu Linux server 8.10 to 9.04 remotely over ssh session?

Be sure that you have all updates applied to Ubuntu 8.10 server before you upgrade. Type the following command to apply updates:
$ sudo apt-get update
$ sudo apt-get upgrade

WARNING! Backup important data, sql and configuration file before server running the following upgrade commands. The following discussion only applies to the SERVER edition. For Ubuntu 9.04 desktop upgrade see this FAQ.

    Thank you for you tip. I tried as you said but it seeemed nothing happened. Wha’t wrong?

    # do-release-upgrade
    Checking for a new ubuntu release
    No new release found

    root@kindy:~# uname -a
    Linux kindy 2.6.24-23-server #1 SMP Wed Apr 1 22:14:30 UTC 2009 x86_64 GNU/Linux

      Run the following and find out your current version:
      lsb_release -a

  • kyanh Apr 25, 2009 @ 13:27

    Thank you Vivek Gite. After running upgrade I still see the 8.04 version as below. I guess that I should change the /etc/apt/source.list. Right?

    lsb_release -a
    No LSB modules are available.
    Distributor ID: Ubuntu
    Description: Ubuntu 8.04.2
    Release: 8.04
    Codename: hardy

  • V.Balaviswanathan Apr 25, 2009 @ 20:57

    Cool one and thanks a lot for the tips

  • roreru Apr 30, 2009 @ 20:40

    I run lsb_release -a and got this
    No LSB modules are available.
    Distributor ID: Ubuntu
    Description: Ubuntu 8.10
    Release: 8.10
    Codename: intrepid
    How come I can’t upgrade to 9.04?

  • rishi May 2, 2009 @ 17:00

    whenever i enter the command that
    sudo do-release-upgrade
    it shows
    no release found
    would u help
    i have done all prequeisites.

  • BDP May 6, 2009 @ 1:55

    For those getting “no release found” try running this instead

    sudo do-release-upgrade -d

    where -d is a shortcut for –devel-release

  • zmjjmz Jan 8, 2010 @ 8:08

    Re: BDP’s advice:
    If you’re running a server, you probably don’t want to run Lucid. That won’t work.

  • gatoguts Feb 13, 2010 @ 11:18

    I tried all the above as well as sudo do-release-upgrade -d and still getting No new release found. Could this be a hardware issue? I have a Dell mini laptop that came prepackaged with 8.04. Could it be that upgrades are not available for my computer?

  • Dakos Feb 18, 2010 @ 22:08

    Gatoguts: Dell Mini 12″ came with Dell’s own version of Ubuntu 8.04 which doesn’t upgrade, and later versions of Ubuntu won’t install. I sent my Dell back in disgust..

    Shame, ‘cos it seemed like a nice netbook..

    (This was pre Karmic, I don’t know if that will install on it. If so you’ll probably have to do a fresh install.)

    • RonS May 28, 2010 @ 12:31

      I have a Dell Mini-12 that came with Vista and I immediately installed Ubuntu 9.04. It worked great but I was never able to get 9.10 to work either as an upgrade or re-install.
      I just installed Ubuntu 10.04 on it and it works even better. Had to install the Broadcom drivers from the deb file on the disk to get wireless to work, but that was the only issue that I encountered.

  • Dakos Feb 18, 2010 @ 22:14

    Also, the question is “How do I upgrade Ubuntu Linux server 8.10 to 9.04 remotely over ssh session?”

    If you follow the instructions here, surely you will loose the SSH connection to your server during the install process and end up in a mess? I’ve tried this twice before and it’s always been a minor disaster where I wished I’d plugged a screen and keyboard directly into the server in the first place. But then I’m an amateur who probably missed something! :)

  • gatoguts Feb 19, 2010 @ 21:10

    Dakos: To do a fresh install, do I need to remove the exisiting Dell system first and then just download from And can I go straight to the latest release, or should I download 8.10 first?

  • Chris Feb 20, 2010 @ 21:24

    As an FYI, I just updated 9.04 raid server to 9.10 via ssh with no problems all. Thank you for supplying the steps.

  • John Mark Apr 9, 2010 @ 19:05

    Here’s a tip I picked up elsewhere, for those of you who get “no release found”

    Edit /etc/update-manager/release-upgrades

    and if you see “Prompt=lts” change it to “Prompt=normal”


  • Brinley Ang Jun 18, 2010 @ 1:38

    If you get this “no release found” and you have “Prompt=lts” in /etc/update-manager/release-upgrades and dont want to change that release setting because of say unattended updates. Then all you need to do is run

    sudo do-release-upgrade –proposed

  • david bushey jr Jul 25, 2010 @ 6:56

    thank you

  • SciFi-Bob Aug 1, 2010 @ 1:15

    This made my server unbootable. Thank you, I now have no internet connection in my home, my wife is bugging me why she can’t connect to facebook, and I sit with a server that only says “Grub (15) file not found..
    WHAT FILE?? What about stating WHAT FILE you are trying to read?
    I hate grub right now., it’s a piece of shit waiting to destroy my network.
    For a developer like me, grub seems like a disaster, programmed by idiots, with no regards to common programming practice.
    You just don’t show a “file not found” message without displaying the file name. No, you don’t.

  • Jacob Oct 10, 2011 @ 19:05

    I have tried ALL of the above, and it still won’t work, I am new to ubuntu, (I was given this computer by my stepdad yesterday, with ubuntu 8.10 on) and as I’d never known of the existence of ubuntu until this computer I must say, I think I even prefer mac to this. Is there anything else I can do to try and upgrade it, or should I bite the bullet and buy windows?

    P.S. I mean no offence to anyone with any of my opinions, and the recent versions may not be bad, but from what I have seen of this, it can’t do anything. If anyone could help I would be very grateful. Thank you.

  • bhavik Apr 10, 2012 @ 5:27
