How to upgrade ubuntu 9.04 Jaunty to 10.04.1 LTS Lucid－小魚缸

First, this link lists all ubuntu releases

Second, a brief intro for how to do

升級 Ubuntu 10.04.1 LTS (Lucid Lynx)

Kirin Lin

昨天晚上升級桌機，今天晚上升級 X60s。

桌機之前有升級到 Ubuntu 9.04 (Jaunty Jackalope)，卻無法直升 Ubuntu 10.04.1 LTS (Lucid Lynx)，需要先升級到 Ubuntu 9.10 (Karmic Koala) 才行，總之下載了很久就是。

而 X60s 雖然自Ubuntu 8.04 LTS (Hardy Heron) 直升 Ubuntu 10.04.1 LTS (Lucid Lynx)，最後剩下幾十個檔案老遇到更新伺服器 403。稍做檢查後把軟體來源（Software Sources）改回主要即可，之前為了什麼換到某個台灣伺服器？不可考…XD

升級完不會自動移除的是 kernel 套件，這次使用 Computer Janitor 來移除，系統裡頭沒什麼重要的東西就試試看。

Third, a detailed description for how to do

官方源内已经没有jaunty(9.04)的文件夹了，已经不再支持jaunty(9.04)
我想升级该如何操作？
进行do-release-upgrade操作时，情况如下，

代码:

chris@csk:~$ sudo lsb_release -a

            No LSB modules are available.

            Distributor ID: Ubuntu

            Description:    Ubuntu 9.04

            Release:        9.04

            Codename:       jaunty

            chris@csk:~$ sudo do-release-upgrade

            Checking for a new ubuntu release

            Done Upgrade tool signature

            Done Upgrade tool

            Done downloading

            extracting 'lucid.tar.gz'

            authenticate 'lucid.tar.gz' against 'lucid.tar.gz.gpg'

            tar: Removing leading `/' from member names

            Reading cache

            Checking package manager

            Can not upgrade

            An upgrade from 'jaunty' to 'lucid' is not supported with this tool.

如果修改sources.list内的版本号强制升级，应将版本号设置为哪个版本？
如果进行强制升级会出现什么问题？(服务器在机房托管)

处理方法：
由于使用do-release-upgrade无法直接从9.04升级至10.04，因为害怕强制升级出现故障，所以决定先从9.04升级至9.10
查看升级包信息
cat /var/lib/update-manager/meta-release 找到以下内容(内容较多，只贴需要部分)

按提示进行升级操作至重启计算机
重启后执行

代码:

do-release-upgrade

升级至10.04

更新完毕

Thank these guys~

後記: 因為遇到GLIBC_2.12的相容性問題, 決定把10.04 Lucid LTS 往上升一版到 10.10 Maverick, upgrader在此 --> wget http://archive.ubuntu.com/ubuntu/dists/maverick-proposed/main/dist-upgrader-all/0.142.23/maverick.tar.gz

BTW, 建議如果要用freenx的人先在10.04就裝好, 不然等到10.10才想到要裝freenx會遇到問題的, 必須在package list裡動手腳(見freenx一文)

Good Luck喔~
