我在 Ubuntu 11.10 上安装了 banshee 2.2.1。我一直想把 banshee 更新到 2.4（昨天发布的），但就是不行。我一直在使用
sudo add-apt-repository ppa:banshee-team/ppa
在终端中，来自 Banshee.fm 网站。但在通过终端运行后，它显示以下内容：
sudo add-apt-repository ppa:banshee-team/ppa
You are about to add the following PPA to your system:
PPA for Banshee Team
This PPA contains the latest stable debs of Banshee for Ubuntu. To install Banshee, you must first enable the PPA on your system:
1. Open Software Sources (System->Administration->Software Sources)
2. Navigate to the "Third Party Sources" tab.
3. Click "Add"
4. Enter the APT line below that corresponds to your Ubuntu version that starts with "deb".
5. Click "Add Source"
6. Click "Close"
7. It will prompt you to reload your software cache. Click "Reload".
8. Now install the package "banshee" from Synaptic, or using the command below:
sudo apt-get install banshee
For those who wish to compile from trunk, add the deb-src line and then run "sudo apt-get build-dep" to install all required dependencies before starting to compile.
Unstable (version which have odd minor version numbers) debs of Banshee can be found here:

我相信我有 ppa，但我不确定。我需要一步一步的过程来获得它，我已经尝试弄清楚了很长时间了……

您已添加 PPA，但它不会自动更新或升级任何内容。
您只需使用更新管理器或通过以下方式进行更新：
sudo apt-get update
sudo apt-get upgrade
