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.Next, install update-manager-core if it is not already installed:
$ sudo apt-get install update-manager-core
Finally, start the upgrade tool, enter:
$ sudo do-release-upgrade
Now, just follow the on-screen instructions to upgrade your server over ssh session.

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 -aThank 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

How come I can’t upgrade to 9.04?
whenever i enter the command that
sudo do-release-upgrade
it shows
no release found
would u help
i have done all prequeisites.
For those getting “no release found” try running this instead
sudo do-release-upgrade -d
where -d is a shortcut for –devel-release
Re: BDP’s advice:
If you’re running a server, you probably don’t want to run Lucid. That won’t work.
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?
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.)
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.
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! :)
Dakos: To do a fresh install, do I need to remove the exisiting Dell system first and then just download from ubuntu.com? And can I go straight to the latest release, or should I download 8.10 first?
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.
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”
HTH.
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
thank you
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.
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.
