在 Ubuntu 21.10 上安装 gnome 40 后 dpkg gnome-settings 配置错误

我运行以下命令在 Ubuntu 21.10 上安装 GNOME Vanilla：

sudo apt install vanilla-gnome-desktop

这成功了，我能够登录 GNOME 40.4。但我收到一个随机的 dpkg 错误，如下所示：

Setting up vanilla-gnome-default-settings (20.04.1) ...
update-alternatives: error: no alternatives for gdm3-theme.gresource

 vanilla-gnome-default-settings
 vanilla-gnome-desktop
E: Sub-process /usr/bin/dpkg returned an error code (1)

使用 Ubuntu DE 和 Gnome DE 时，此问题仍然存在。Gnome 设置本身似乎可以正常工作。在此之后，现在我在任何 apt 命令之后都会收到以下错误：

Setting up vanilla-gnome-default-settings (20.04.1) ...
update-alternatives: error: no alternatives for gdm3-theme.gresource

我尝试运行sudo dpkg --configure -a，但发生了以下情况：

$ sudo dpkg --configure -a

我在 Gnome Boxes 中安装的 Ubuntu 21.10 上运行所有这些（使用内置操作系统下载选项下载）

这是一个众所周知的 bug。请参阅 #1935767。

看一眼评论3经过保罗·布罗德黑德（代码格式我自己的）：

我对此有一个手动修复。

编辑 ” /var/lib/dpkg/info/vanilla-gnome-default-settings.postinst”

gdm3-theme.gresource改成” gdm-theme.gresource”

然后 ” sudo apt install -f”

原始的 gnome 设置现在可以按预期工作。

您可以按如下方式修复它。

  1. /var/lib/dpkg/info/vanilla-gnome-default-settings.postinst用文本编辑器打开。

  2. 查找gdm3-theme.gresource并替换为gdm-theme.gresource

  3. 運行sudo apt -f install去修復。

另外，这里有上述步骤的易于复制粘贴的一行版本：

sudo sed -i "s/gdm3-theme.gresource/gdm-theme.gresource/" /var/lib/dpkg/info/vanilla-gnome-default-settings.postinst && sudo apt -f install
