No Dock in Ubuntu 18.04

  • 772

I can only see default GNOME Dock when I click Activities:

What I am already trying to do:

  1. I try remove GNOME files like .gnome .gnome2 .gconf .gconfd .metacity
  2. I disable all installed Gnome Extensions with Gnome Tweaks GUI.
  3. I 'Reset to Defaults' all Gnome Tweaks.
  4. I reset all changes in gnome with dconf reset -f /org/gnome/
  5. I try install sudo apt install gnome-shell-extension-ubuntu-dock but get message it already installed: gnome-shell-extension-ubuntu-dock is already the newest version (0.9.1ubuntu18.04.3).
  6. Thousands restarts and log-out's..
gnome-shell ubuntu-dock 18.04

    I have personally experienced this many times.. as the first thing I do in lot of fresh Installations of Ubuntu 18.04 is to run sudo rm -rf /usr/share/gnome-shell/extenisons/* This will remove the pre-enabled extensions but apt still thinks this is not removed from the system and that's why it says gnome-shell-extension-ubuntu-dock is already the newest version (0.9.1ubuntu18.04.3).

    Example:

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

pratap@i7-4770U:~$ sudo rm -rf /usr/share/gnome-shell/extensions/*

    so, the workaround is to purge the extension with the below command

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

    and then re-install with

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

    between these two commands, I am not sure.. whether these commands are required or not

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

    and then Install it from any tty, I did not remember it when I came across with this situation.. but guessing is that sudo apt purge gnome-shell-extension-ubuntu-dock command will remove ubuntu-desktop also
