现在用的这个系统是直接dapper安装的,没有通过升级。不过升级的步骤并不复杂啊!
1.修改/etc/apt/source.list中的源,使用dapper的源代替;
2.apt-get update
3.apt-get dist-upgrade
4.reboot

Upgrading from Ubuntu 5.10
A new version of the Update Manager application has entered breezy-updates which can upgrade your entire system in a few simple steps.
To perform the upgrade:
1.
Update your system to ensure that you have the latest version of Update Manager and associated packages. The necessary versions are available from the breezy-updates repository, which is enabled by default.
2.
Run the following command (either via ALT-F2 or a terminal):
gksudo "update-manager -d"
*
The "-d" switch instructs Update Manager to consider pre-release versions, including this Beta release. Without this switch, only official, final releases will be considered.
If you have a working network connection, it should then inform you about a new release and offer to upgrade your system.
