1 如何安装新应用程序？从哪里得到它们？

最简单的方法是用Synaptic，还有其它方法比如apt-get。ubuntu维护着一些公用在线软件库（repositories）。库中的程序经检验无病毒及间谍软件，但仍可能存在bugs。

2 System->Administration->Synaptic Package Manager启动Synaptic。

3 设定更多的系统/应用程序更新源。ubuntu默认的更新源是basic and security update repositories。而可用的更新源共有四种： Officially supported, Restricted copyright, Community maintained (Universe) and Non-free (Multiverse).使用System->Administration->Synaptic Package Manager->Settings->Repositories->Settings->Show disabled software sources->Close->Add,然后选中需要的更新源，保存。

4 Backports源为当前ubuntu稳定版本提供一些比较新的软件。加入backports： 启动Synaptic。System->Administration->Synaptic Package Manager。 在Synaptic中选择Settings-> Repositories.

点击Add，然后点击Custom.

在下面的框中输入：deb http://archive.ubuntu.com/ubuntu breezy-backports main universe multiverse restricted

单击Ok。在询问是否重新载入时单击Yes. 5

To backup downloaded repositories cache:

mkdir -p $HOME/backup/var/lib/

sudo cp -R /var/lib/apt/ $HOME/backup/var/lib/ mkdir -p $HOME/backup/var/cache/

sudo cp -R /var/cache/apt/ $HOME/backup/var/cache/ mkdir -p $HOME/backup/etc/apt

sudo cp -R /etc/apt/ $HOME/backup/etc/ sudo chown -R $USER $HOME/backup/

To restore downloaded repositories cache:

sudo cp -fR $HOME/backup/var/* /var/

sudo cp -fR $HOME/backup/etc/apt/* /etc/apt/

6 使用apt-get手动更新ubuntu。 sudo apt-get update sudo apt-get upgrade
