Updating 8.10 to 9.04

[hellnoire]

I figure since there is one day left, there is no harm in posting this.

If you want to upgrade From Ubuntu Intrepid (8.10) to Jaunty (9.04) use this tutorial for faster upgrades.We are going to use apt-p2p for this tutorial.apt-p2p is a p2p proxy for apt dowloads, it will act as a proxy between apt requests and a repository server, downloading any request files from peers (if possible), else will fallback to direct HTTP download. In general, apt-p2p save bandwidth, use limited cpu and memory resources and reduce congestion on the ubuntu mirrors.apt-p2p will get the request files from peers, therefore, it will avoid the congestion on the ubuntu mirrors.

Note:- This is only for advanced users, IF DONE WRONG, IT CAN AND WILL MESS UP YOUR OPERATING SYSTEM.
apt-p2p features

* Downloads from peers, increasing the available bandwidth to the user

* Reduces the bandwidth requirements needed to setup a repository of packages

* Seamlessly integrates with the current APT tool

* Automatically falls back to downloading from an HTTP mirror when peers are not available

* Builds on other already existing tools where possible

* Fast and requires limited CPU and memory

* Will try to download any file it can find a hash for from peers (including Packages.bz2, Sources.gz, …)

Install apt-p2p in ubuntu

sudo aptitude install apt-p2p

This will complete the installation.

Configuring apt-p2p

First you need to take a backup of your source list

sudo cp /etc/apt/sources.list /etc/apt/sources.list.backup

Edit sources.list file

gedit /etc/apt/sources.list

Add “localhost:9977/ after the “http://” save and exit the file

deb http://localhost:9977/archive.canonical.com/ubuntu intrepid partner
    deb-src http://localhost:9977/archive.canonical.com/ubuntu intrepid partner
    deb http://localhost:9977/*mirror-address*/ubuntu/ intrepid main universe restricted multiverse
    deb-src http://localhost:9977/*mirror-address*/ubuntu/ intrepid main universe restricted multiverse

So basically just insert “localhost:9977″ after the “http://” and where **mirror-address** is the address of the mirror

Now remove the cache files using the following command

sudo rm -rf /var/cache/apt-p2p/cache/*

Update the source list file using the following command

sudo apt-get update

Start upgrade from Interpid to Jaunty

sudo update-manager

If you want to Check peers, downloads and uploads speed and DHT statistics Open Internet browser,

go to

http://localhost:9977

KEEP IN MIND THIS IS FOR ADVANCED USERS ONLY. If you still have a limited experience with Linux, then DON'T DO IT OR ASK HOW TO. This is as simple as this can be made.

Another way to update to Ubuntu 9.04 is by the HTTP method. This is slower, but not only easier, but more of a chance of success without errors. Simply go System>Adminstration>Software Sources and change the drop down to Normal Releases as seen here:

You should now be able to update via the Update Manager.

The third, and perhaps second easiest way is to either have the CD shipped to you or download and burn to a disk, then boot from it. Once booted, you should see an option to upgrade the current OS. Choose that and install it that way. Since it doesn't deal with the internet, it is going to be safer then the others.

Finally, the fourth way, the easiest way: back up your data and install the new version over top of the old one. Doesn't get any easier.

REMEMBER! Run these commands in a day, when the new version of Ubuntu is official! And for the love of cod, DON'T use the Apt-p2p unless you know exactly what you're doing. There are safer ways to update, as you can see.

Apt-p2p tut written by UbuntuGeek. I could have stolen last year's tut from TorrentFreak but as you could guess, it's out of date.

I uninstall Ubuntu cause of changing grub loader cause a lot problem to me, will install back when 9.04 version out.

Great. Now I can't download as I am sure streamyx will throttle its speed.

That is it? The 2nd way? That I can do. Er, don't need to put this into he place like when I did my Open Office?

deb http://localhost:9977/archive.canonical.com/ubuntu intrepid partner
deb-src http://localhost:9977/archive.canonical.com/ubuntu intrepid partner
deb http://localhost:9977/*mirror-address*/ubuntu/ intrepid main universe restricted multiverse
deb-src http://localhost:9977/*mirror-address*/ubuntu/ intrepid main universe restricted multiverse

Lunar, just request a disc tomorrow, and install when the disc come. Or download the ISO but i think the speed will be reduced a lot as many people will get it.

[hellnoire]

Lunar, I don't think you'd advanced enough to even worry about apt-p2p, no offense. And the throttling of Streamyx would kill your upgrade. So either request the disk or download via Update Manager. Or you could do step 4 Lol, but honestly, I think you've gone though enough formating, so that's why I posted this. If you aren't using apt-p2p, you don't need to add to your sources.

YuMeng, if you mean the standard HTTP way, that will be on high demand for the next two or three days. That's why I'm downloading via torrent

[kronos_fir18]

nice post hellnoire...btw,if i'm trying the p2p,then somehow i screw it up,can i reformat back?

[hellnoire]

You'd need to reinstall via CD if the P2P messes up on you, Kronos. That's often the easiest way to do so.

[YuMeng]

Unless you will waste the money to buy CD.

Why isn't it the update manager working? I set the setting as shown by Hellnoire. My mirror server is located in Taiwan,

Do I need to add in any other stuff?

Hi all,
I installed Ubuntu 8.10 thanks to WUBI on my desktop PC with XP SP3.
My question is: do you think I can upgrade to Ubuntu 9.0.4 by the HTTP method which hellnoire kindly explained?
Sorry, I'm not a Linux advanced user.

Thanks in advance
