我在安装 Debian 时意外安装了桌面环境。现在我试图删除它,但没有成功:tasksel remove desktop
仅更改i
为u
if tasksel --list-tasks
。
sudo apt-get remove task-desktop
也不起作用:根本没有输出。
我甚至看不到 task-desktop 包里面有什么元包。
我只想获得一个 Debian 服务器,而不是桌面。
答案1
我会按照优先顺序做什么:
使用 PXE + 重新启动并重新安装我的服务器
preseed
。这样,您就有了一种可重复的安装方法,无需容易出错的人为干预。花在设置上的时间在您第二次使用它时会得到回报。如果无法重新安装:
a. 我将尝试找出任务选择安装了哪些软件包,首先列出可用的选择:
$ tasksel --list-tasks u desktop Debian desktop environment u web-server Web server u print-server Print server u database-server SQL database u dns-server DNS Server u file-server File server u mail-server Mail server u ssh-server SSH server u laptop Laptop
b. 接下来列出具体选择:
$ tasksel --task-packages desktop task-desktop
c. 显示包元数据以找出其依赖项:
$ aptitude show task-desktop Package: task-desktop State: not installed Version: 3.16 Priority: optional Section: tasks Maintainer: Debian Install System Team <[email protected]> Architecture: all Uncompressed Size: 21.5 k Depends: tasksel, xorg, xserver-xorg-video-all, xserver-xorg-input-all, desktop-base, menu Recommends: task-gnome-desktop | task-kde-desktop | task-lxde-desktop | task-xfce-desktop, xdg-utils, avahi-daemon, libnss-mdns, anacron, libgl1-mesa-dri, eject, iw, alsa-utils, alsa-base, pm-utils Description: Debian desktop environment This task package is used to install the Debian desktop.
d.您可以对每个依赖项重复最后一步,或者使用其他工具直接查找该信息:
$ apt-cache depends task-desktop task-desktop Depends: tasksel Depends: xorg Depends: xserver-xorg-video-all Depends: xserver-xorg-input-all Depends: desktop-base Depends: menu |Recommends: task-gnome-desktop |Recommends: task-kde-desktop |Recommends: task-lxde-desktop Recommends: task-xfce-desktop Recommends: xdg-utils Recommends: avahi-daemon Recommends: libnss-mdns Recommends: anacron Recommends: libgl1-mesa-dri Recommends: eject Recommends: iw Recommends: alsa-utils Recommends: alsa-base Recommends: pm-utils
e. 有一些工具可以列出正向和反向依赖关系,并带有输出过滤选项:
$ apt-rdepends -r task-desktop --state-follow=Installed Reading package lists... Done Building dependency tree Reading state information... Done task-desktop Reverse Depends: task-gnome-desktop (3.16) Reverse Depends: task-kde-desktop (3.16) Reverse Depends: task-lxde-desktop (3.16) Reverse Depends: task-xfce-desktop (3.16) $ apt-rdepends task-desktop --state-follow=Installed Reading package lists... Done Building dependency tree Reading state information... Done task-desktop Depends: desktop-base Depends: menu Depends: tasksel Depends: xorg Depends: xserver-xorg-input-all Depends: xserver-xorg-video-all menu Depends: dpkg (>= 1.15.4) Depends: install-info Depends: libc6 (>= 2.2.5) Depends: libgcc1 (>= 1:4.1.1) Depends: libstdc++6 (>= 4.6) dpkg PreDepends: libbz2-1.0 PreDepends: libc6 (>= 2.11) PreDepends: liblzma5 (>= 5.1.1alpha+20120614) PreDepends: libselinux1 (>= 1.32) PreDepends: tar (>= 1.23) PreDepends: zlib1g (>= 1:1.1.4)
f. 此时,您可以开始卸载东西,使用类似工具
orphaner
来确保没有留下任何内容,或者开始用更好的眼光看待选项 1。
