4. 放置非官方源的包不完整,可在为不添加官方源

deb http://archive.ubuntu.org.cn/ubuntu-cn/ feisty main restricted universe multiverse

5. 更新源

sudo apt-get update

6. 更新软件

sudo apt-get dist-upgrade
sudo apt-get upgrade

由于包与包之间存在各种依赖关系。upgrade只是简单的更新包,不管这些依赖,它不和添加包,或是删除包。而dist-upgrade可以根据依赖关系的变化,添加包,删除包。upgrade:系统将现有的Package升级,如果有相依性的问题,而此相依性需要安装其它新的Package或影响到其它Package的相依性时,此Package就不会被升级,会保留下来. dist-upgrade:可以聪明的解决相依性的问题,如果有相依性问题,需要安装/移除新的Package,就会试着去安装/移除它. (所以通常这个会被认为是有点风险的升级)

7. 常见的修复安装命令

sudo apt-get -f install
