ubuntu 9.04 升級

 早期安裝ubuntu 9.04 jaunty 版本，不再受到ubuntu的支持。由於jaunty與現行的lucid版本之間，還有karmic 版本，所以不能直接使用do-release-upgrade 升級9.04. 升級的具體步驟如下，

Ubuntu version: jaunty, Ubuntu 9.04 desktop

 

• Use clonezilla to backup the system
• Remove user specific PPA

Ref: http://askubuntu.com/questions/307/how-can-ppas-be-removed

• Upgrade to karmic

Download karmic (ubuntu-9.10-alternate-i386.iso)

Ø       sudo mount -o loop ~/ubuntu-9.10-alternate-i386.iso /media/cdrom

Ø       gksu "sh /media/cdrom/cdromupgrade"

Ø       sudo do-release-upgrade -d

 

• Check version

Ø      lsb_release –a

Release:         10.04

Codename:     lucid
