Upgrade dapper to hardy

After dapper image is loaded to my server, now the time for upgrade begin:

1. root@server:~# vim /etc/apt/sources.list
delete all lines, then type these:

deb http://us.archive.ubuntu.com/ubuntu dapper main restricted multiverse universe
deb http://us.archive.ubuntu.com/ubuntu dapper-updates main restricted multiverse universe
deb http://us.archive.ubuntu.com/ubuntu dapper-security main restricted multiverse universe

deb-src http://us.archive.ubuntu.com/ubuntu dapper main restricted multiverse universe
deb-src http://us.archive.ubuntu.com/ubuntu dapper-updates main restricted multiverse universe
deb-src http://us.archive.ubuntu.com/ubuntu dapper-security main restricted multiverse universe

2. run these commands to update your changes above.

root@server:~# apt-get update
root@server:~# apt-get upgrade
root@server:~# apt-get dist-upgrade

3. install update-manager-core.

root@server:~# apt-get install update-manager-core

4. do the upgrade, and follow the instructions there.

root@server:~# do-release-upgrade -d

5. you may clean up the packages archive using:

root@server:~# apt-get clean


Now, you have dapper upgraded to hardy. Time to play with my upgraded vps now!

Note:

There is a locale setting error occurs like in the previous vps provider. However, the soltion I wrote in the past is not working this time. I found new solution here: https://bugs.launchpad.net/ubuntu/+source/langpack-locales/+bug/63687

Don't forget, in vps usually you access the server using root. If you have access other than root, don't forget to put sudo before the commands or sudo password root and sudo su.
