我想在 Ubuntu 12.04 上安装 Trinity（KDE 3.x 的分支）。我尝试添加 PPA 并执行sudo apt-get install kubuntu-default-settings-trinity kubuntu-desktop-trinity，但出现错误：

我在 PPA 的概览页面上没有看到第 5 步，请查找签名密钥标题。您将看到类似以下内容：
1024R/72D340A3（这是什么？）
复制斜线后的部分但不包括帮助链接；例如仅复制 72D340A3
如果您想帮助我，请访问以下链接：https://quickbuild.pearsoncomputing.net/~trinity/+archive/trinity-nightly-builds/
答案1
目前没有适用于 ubuntu 12.04 的软件包。您收到此错误的原因是您正在安装的软件包不存在。您可以尝试使用 11.10 说明安装 ubuntu，但不能保证它有效或不会导致安装问题：

答案2
现在有一个名为“Trinity”的新桌面环境，它基本上是 KDE3 的进一步开发。
您可以按照以下说明进行安装。
sudo gedit /etc/apt/sources.list
将这些行添加到您的源列表的末尾，如果您正在运行旧版本的 ubuntu，请在继续之前查看此页面。
deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/ubuntu/dists/precise/ main
deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-v3.5.13/ubuntu/dists/precise/ main
deb http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps-v3.5.13/ubuntu/dists/precise main
deb-src http://ppa.quickbuild.pearsoncomputing.net/trinity/trinity-builddeps-v3.5.13/ubuntu/dists/precise main
接下来您需要添加 GPG 签名密钥。
sudo apt-key adv –keyserver keyserver.quickbuild.pearsoncomputing.net –recv-keys 2B8638D0
接下来只需确保您已更新并安装 Trinity。
sudo apt-get update
sudo apt-get install kubuntu-default-settings-trinity kubuntu-desktop-trinity
就这样，您现在可以注销、切换会话并登录 KDE3。尽情享受吧！=)

它不起作用，看看错误：
sudo apt-get update
E: Línea 66 mal formada en la lista de fuentes /etc/apt/sources.list (análisis de dist)
