ubuntu10.04升级到10.10

ubuntu为什么要升级呢？原因是多种多样的：极客心理、为了更好的支持硬件、修复系统Bug等等。

怎么样升级呢？其实很简单，就像是升级一个软件一样简单：添加源，更新，升级。

好了就直接上过程了：

代码：sudo cp /etc/apt/sources.list /etc/apt/sources.list.old

代码：sudo gedit /etc/apt/sources.list

把用下面的源替换原来的：

deb lucid main restricted universe multiverse

deb lucid-security main restricted universe multiverse

deb lucid-updates main restricted universe multiverse

deb lucid-backports main restricted universe multiverse

deb lucid-proposed main restricted universe multiverse

deb-src lucid main restricted universe multiverse

deb-src lucid-security main restricted universe multiverse

deb-src lucid-updates main restricted universe multiverse

deb-src lucid-backports main restricted universe multiverse

deb-src lucid-proposed main restricted universe multiverse

代码：sudo apt-get update

代码：sudo apt-get dist-update(或sudo update-manager -d )

然后就能升级啦！个人觉得，升级完后更好用了：

更新管理器布局更合理，图标更美观了。
