sudo apt-get install xubuntu-desktop，而你已经执行过了。如何将Ubuntu转换为Xubuntu讨论了你将获得的更改，所以你必须编辑命令并查看可能需要的内容。背景
k/x/ubuntu-desktop软件包是元软件包/1/。
“这些软件包不包含实际的软件，它们只是依赖于其他软件包的安装。这种设置允许通过仅选择适当的元软件包来安装整套软件。”
Kubuntu桌面/2/软件包依赖/推荐/4/许多软件包。其中一些可能与其他桌面共享。
你是如何安装这些桌面的？
Synaptic和Muon软件包管理器会保留历史日志或解析dpkg日志。
从dpkg日志（命令行）检查已安装/更新/删除的软件包：
最近的状态日志：
grep "status installed" /var/log/dpkg.log
grep upgrade /var/log/dpkg.log
grep remove /var/log/dpkg.log
grep "status installed" /var/log/dpkg.log.1
grep upgrade /var/log/dpkg.log.1
grep remove /var/log/dpkg.log.1
最古老的日志-旋转的dpkg日志（已打包）：dpkg.log.2.gz，dpkg.log.3.gz...
您可以查看日志文件并搜索xubuntu-desktop，kubuntu-desktop等安装了什么。
在测试/实验时
保留自己的日志。有一个logsave命令。
:~$ man logsave /3/
NAME
logsave - save the output of a command in a logfile
SYNOPSIS
logsave [ -asv ] logfile cmd_prog [ ... ]
DESCRIPTION
The logsave program will execute cmd_prog with the specified argument(s),
and save a copy of its output to logfile.
If the containing directory for logfile does not exist, logsave will
accumulate the output in memory until it can be
written out. A copy of the output will also be written to standard output.
logsave testing_kubuntu-desktop.log sudo apt-get install kubuntu-desktop
https://wiki.ubuntu.com/JauntyJackalope/ReleaseNotes
默认安装的推荐软件包
根据 Debian 政策手册（其中写道“‘Recommends’ 字段应列出在所有但不寻常的安装中与此软件包一起找到的软件包”），软件包管理系统现在默认安装其他已安装软件包的 Recommends: 字段中列出的软件包，以及 Depends:。如果您想避免特定软件包的这种情况，请使用 apt-get --no-install-recommends；如果您想使其永久生效，请在 /etc/apt/apt.conf 中设置 APT::Install-Recommends "false"。请注意，这可能会导致某些程序缺少功能。
（此更改是在 Ubuntu 8.10 中进行的。）
我在12.04 LTS中安装Lubuntu桌面后，决定不使用它，并计划卸载它。遵循上述部分指示时，出现了错误。（抱歉，我从未保存屏幕截图）。
由于Lubuntu桌面已经损坏，我使用了Synaptic软件包管理器，首先恢复它（实际上是多余的步骤），然后彻底删除它。
这种方法简单而且结果完美，移除了所有内容。
