How to upgrade a remote server from 8.10 to newer version?

I have a remote server still running Ubuntu 8.10 9.04 that I can only access via SSH.

If I run apt-get update I get a bunch of 404 errors on the packages. I've asked a few questions on Server Fault but got nowhere. Here's what I've done:

1. Run apt-get update which returns errors like:

   Err http://gb.archive.ubuntu.com intrepid/main Packages 404 Not Found
   [and same for many other packages]

2. Run do-release-upgrade which returns:

   Checking for a new ubuntu release
   Failed Upgrade tool signature
   Failed Upgrade tool
   Done downloading
   extracting 'jaunty.tar.gz'
   Failed to extract
   Extracting the upgrade failed. There may be a problem with the network or with the server.

3. Edited /etc/update-manager/release-upgrades and changed from Prompt=normal to Prompt=lts (as suggested here). Running do-release-upgrade after this returns:

   Checking for a new ubuntu release
   current dist not found in meta-release file
   No new release found

4. (Updated) I have followed the advice in this question and changed /etc/apt/sources.list to refer to jaunty instead of intrepid. However, that distro is not online anymore either. A comment there says I have to upgrade in chronological order...

So basically, it seems like I cannot upgrade because my current distro is out of date and not supported. Is there a way to upgrade direct to 10.x or 11.x? Note, as this is a server I only have command-line access.

UPDATE 24/11: I have managed to upgrade from 8.10 to 9.04. Ubuntu's EOL Upgrades page provides some alternate URLs for apt sources. I also needed to update /var/lib/update-manager/meta-release to point to the old-releases server too.

However, now I cannot upgrade from 9.04 to 9.10. Running do-release-upgrade produces the same error as #2 above, except it "Failed to fetch" (the URLs in meta-release are valid). The Ubuntu Jaunty upgrade page says it's necessary to upgrade using a CD image. I followed the instructions here, but it didn't work:

A fatal error occurred

Please report this as a bug and include the files /var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log in your report. The upgrade is now aborted. Your original sources.list was saved in /etc/apt/sources.list.distUpgrade.

Traceback (most recent call last):

OSError: [Errno 2] No such file or directory: './plugins'

It does say to report the bug, but since this is an old unsupported release I don't know if it's worth doing. However, is there a way round this, to upgrade from 9.04 to 9.10 (And then finally to 10.04 LTS.)

Solution 1:

Update from 'Ubuntu Server 9.04' (Jaunty) to 'Ubuntu Server 10.04 LTS' (Lucid).

based on:

https://help.ubuntu.com/community/LucidUpgrades

http://echenh.blogspot.com/2010/04/how-to-upgrade-ubuntu-server-904-to-910.html

Step 1: install update-manager-core

sudo apt-get update && sudo apt-get upgrade

sudo apt-get install update-manager-core

Step 2: Update from 9.04 (Jaunty) to 9.10 (Karmic)

edit /etc/apt/sources.list to replace "jaunty" with "karmic"

sudo apt-get update
sudo do-release-upgrade

Step 3: Update 9.10 (Karmic) to 10.04 LTS (Lucid)

edit /etc/update-manager/release-upgrades and set Prompt=lts

file should (at minimum) contain:

[DEFAULT]
Prompt=lts

edit /etc/apt/sources.list to replace "karmic" with "lucid"

sudo apt-get update
sudo do-release-upgrade

ADDITIONAL NOTES:

To check your server version: (at each stage)

lsb_release -a
