在本页顶部 -https://wiki.ubuntu.com/UbuntuStudio/PackageList它显示 =OUTDATED=。我不确定这是指整个页面（以及为什么此安装不起作用）还是仅指其中的第一件事（ubuntustudio-desktop）。

最好的办法：
sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu trusty-security main universe" && sudo apt-get update
然后，
sudo apt-get install ubuntustudio-audio
如果上述方法不起作用，另一种方法是手动下载软件包，然后从那里安装。操作如下：
mkdir ~/Downloads/ubuntustudio && cd ~/Downloads/ubuntustudio
手动下载以下软件包（仍在文件夹中~/Downloads/ubuntustudio）：
security.ubuntu.com libavdevice-extra-53
wget -c http://security.ubuntu.com/ubuntu/pool/universe/liba/libav/libavdevice-extra-53_9.18-0ubuntu0.14.04.1_all.deb
security.ubuntu.com libavfilter-extra-3
wget -c http://security.ubuntu.com/ubuntu/pool/universe/liba/libav/libavfilter-extra-3_9.18-0ubuntu0.14.04.1_all.deb
security.ubuntu.com libavformat-extra-54
wget -c http://security.ubuntu.com/ubuntu/pool/universe/liba/libav/libavformat-extra-54_9.18-0ubuntu0.14.04.1_all.deb
security.ubuntu.com libavutil-extra-52
wget -c http://security.ubuntu.com/ubuntu/pool/universe/liba/libav/libavutil-extra-52_9.18-0ubuntu0.14.04.1_all.deb
security.ubuntu.com libswscale-extra-2
wget -c http://security.ubuntu.com/ubuntu/pool/universe/liba/libav/libswscale-extra-2_9.18-0ubuntu0.14.04.1_all.deb
然后，运行以下命令进行安装：
sudo dpkg -i *.deb
为了满足所有依赖关系，请执行以下操作：
sudo apt-get -f install
