我正在尝试做的事情：

  1. 我尝试删除 GNOME 文件，例如.gnome .gnome2 .gconf .gconfd .metacity
  2. 我禁用所有已安装的 Gnome 扩展Gnome 调整图形用户界面。
  3. 我全部“重置为默认值”Gnome 调整。
  4. 我使用以下命令重置了 gnome 中的所有更改dconf reset -f /org/gnome/
  5. 我尝试安装sudo apt install gnome-shell-extension-ubuntu-dock但收到已安装的消息：gnome-shell-extension-ubuntu-dock is already the newest version (0.9.1ubuntu18.04.3).
  6. 数千次重启和注销......

我个人已经经历过很多次了，因为我在很多全新安装的 Ubuntu 18.04 中做的第一件事就是运行，sudo rm -rf /usr/share/gnome-shell/extenisons/*这将删除预先启用的扩展，但 apt 仍然认为这并没有从系统中删除，这就是为什么它说gnome-shell-extension-ubuntu-dock is already the newest version (0.9.1ubuntu18.04.3).

例子：

pratap@i7-4770U:~$ ls /usr/share/gnome-shell/extensions/

因此，解决方法是使用以下命令清除扩展

sudo apt purge gnome-shell-extension-ubuntu-dock

然后重新安装

sudo apt install gnome-shell-extension-ubuntu-dock

在这两个命令之间，我不确定..这些命令是否是必需的。

sudo apt autoremove && sudo apt autoclean
gnome-session-logout

然后从任何 tty 安装它，当我遇到这种情况时我不记得了。但猜测该sudo apt purge gnome-shell-extension-ubuntu-dock命令也会ubuntu-desktop删除
