Ubuntu11.10 E: Unable to locate package ubuntu-restricted-extras

最近在ubuntu11.10下安装支持多媒体播放的插件时遇到一些问题,在此小记一下。

首先是ubuntu11.10的安装,基本上是一键安装,在此不细说。

1.此版本和以前使用的ubuntu版本风格不太一致,为此在使用时一度不太习惯。

1)软件源服务器的选择

在左侧列表中有一个System  Settings,点击进入有3大选项,选择System里面的Software Sources,出现一个对话框,第一项为Ubuntu Software,此项里有一个DownLoad From选择中国服务器mirrors.163.com(网易)服务源,保存退出。

2)终端的使用

终端的使用不在像以前的版本一样,直接右键桌面就可以出现。Ubuntu11.10使用快捷键Ctrl+Atrl+T,然后可以将终端锁定在左侧的菜单栏里,方便使用。

 

2.安装插件

使用命令

sudo apt-get install ubuntu-restricted-extras
时出现错误:
E: Unable to locate package ubuntu-restricted-extras
即找不到安装的包,在网上找资料,得到的答案是
sudo apt-get update
sudo apt-get upgrade
在使用sudo apt-get update命令时遇到问题
E: Unable to lock directory /var/lib/apt/lists/
查资料得到方法:
sudo rm /var/lib/apt/lists/lock
测试通过!
在sudo apt-get update的过程中遇到问题:

继续找资料,在chaihuasong的博客里名为 ubuntu下sudo apt-get update Sources 404 Not Found [IP: 91.189.92.200 80]解决办法

里获得答案:

把以下内容复制、粘贴到etc/apt/sources.list文件里的最开始部分,保存并退出。

 1 deb http://mirrors.163.com/ubuntu/ lucid main restricted universe multiverse
 2 deb http://mirrors.163.com/ubuntu/ lucid-security main restricted universe multiverse
 3 deb http://mirrors.163.com/ubuntu/ lucid-updates main restricted universe multiverse
 4 deb http://mirrors.163.com/ubuntu/ lucid-proposed main restricted universe multiverse
 5 deb http://mirrors.163.com/ubuntu/ lucid-backports main restricted universe multiverse
 6 deb-src http://mirrors.163.com/ubuntu/ lucid main restricted universe multiverse
 7 deb-src http://mirrors.163.com/ubuntu/ lucid-security main restricted universe multiverse
 8 deb-src http://mirrors.163.com/ubuntu/ lucid-updates main restricted universe multiverse
 9 deb-src http://mirrors.163.com/ubuntu/ lucid-proposed main restricted universe multiverse
10 deb-src http://mirrors.163.com/ubuntu/ lucid-backports main restricted universe multiverse 

测试通过。(虽然在更新的过程中仍然有提示很多package失败和错误)

然后使用命令:

sudo apt-get update

sudo apt-get upgrade

sudo apt-get install ubuntu-restricted-extras

即支持多媒体播放的插件安装成功!
