satimis · 07-20-2012, 07:51 AM

Hi all,

Following guide;
Upgrade to Ubuntu 12.04 from Ubuntu 10.04 via the Terminal
http://www.liberiangeek.net/2012/04/...-the-terminal/

worked for me to upgrade all Ubuntu 10.04 to 12.04 on all VMs of VirtualBox.

But it didn't work on Guests of KVM.

$ sudo do-release-upgrade

Code:

Checking for a new ubuntu release
No new release found

$ lsb_release -a

Code:

NO LSB modules are available
Distributor ID: Ubuntu
Description:  Ubuntu 10.04.4 LTS
Release:  10.04
Codename:  lucid

Pls help. TIA

B.R.

I looked at your "Liberian Geek" tutorial, and it wasn't very good... they gave bad advice about changing /etc/update-manager/release-upgrades from "prompt=lts" to "prompt=normal"... seems to me that is the exact opposite of what you need to go from LTS to LTS.

Maybe try again using the official instructions from Ubuntu.com?

Hi,

Thanks for your advice.

We can't upgrade 10.04 direct to 12.04 on Internet. We must go through;
10.04 -> 10.11 -> 11.04 -> 11.10 -> 12.04

That guide works seamlessly.

On Virtual Box:
I can upgrade all 10.04 VMs (desktop and server) to 12.04 without problem.

On KVM
I can only upgrade 10.04 guests (desktop) to 12.04 without problem. But failed to upgrade 10.04 (server) to 12.04, alwaying saying "no upgrade found".

The only difference is KVM 32bit (host 32bit Debian 6.0 desktop) and VirtualBox 64bit (host 64bit Ubuntu 12.04 desktop)

I can't resolve.

You can upgrade directly from 10.04 to 12.04 in one step if you follow the official upgrade instructions from Ubuntu.com (link in my post above). That page also has instructions for upgrading your Server install.

Give it a try, and if it doesn't work, copy & paste full terminal output of the failed upgrade so I can try to help you.

I tried many times on 3 servers according to;
Network Upgrade for Ubuntu Servers (Recommended)

Set
Prompt=normal

also
Prompt=lts

Ran;
$ sudo do-release-upgrade

also
$ sudo do-release-upgrade -d

All complain "No new release found"

Is there a reason you are summarizing the terminal output instead of copying & pasting so perhaps one of us can spot a detail you overlooked?

Anyway it looks like you skipped step 1:

Code:

sudo apt-get install update-manager-core

And maybe you didn't read:

Note that if you're upgrading from 10.04 LTS, do-release-upgrade will complain "No new release found" until 12.04.1 is released. To force an upgrade, use the -d option. See Ask Ubuntu for more information.

Your "Liberian Geek" tutorial omitted this important information; this is why it's always good to use the official Ubuntu documentation.

This is server without graphic.

What I don't understand is why the steps work seamlessly on Ubuntu server running on VMs of VirtualBox. They don't work on Ubuntu server running on guests of KVM.

I don't understand either, because you haven't given enough information. My advice is to wait until 12.04.1, at which time a 10.04 to 12.04 server upgrade will be tested and recommended (the -d flag, signifying "development/testing," will no longer be required).
