I am trying to install this GNOME Shell extension as shown in this answer, however even though I press the switch to make it On rather than Off and I click Install on the little dialog that I get, when I refresh the page it is Off again and there is no sign of it in gnome-tweak-tool.

I have tried installing other extensions the same way and there is no problem, so why am I unable to install this one? I am running Ubuntu GNOME 15.10 with GNOME 3.18.

Works here on 3.16 (which I guessed you had originally as by default 15.10 should have 3.16 (see here for a reason))... I don't think it supports 3.18 from the extension page (When you have a 'unsupported' shell version for that extension, it won't give any informative errors, which is STUPID).

As a workaround (may not work), you can download the source of the extension from here (Click 'Download repository'), then execute build.sh in the extracted source's directory (cd into from termial, or use 'Open in terminal'). After that, you can extract the ShellTile@emasab.it.zip file to ~/.local/share/gnome-shell/extensions/.

Place it so the metadata file is at: ~/.local/share/gnome-shell/extensions/ShellTile@emasab.it/metadata.json. You need to ensure the metadata file contains your gnome shell version - example: 

{
  "_generated": "Generated by SweetTooth, do not edit", 
  "description": "A tiling window extension for GNOME Shell. Just move a window over another one, holding down the Control key, and you'll see the magic! Grouped windows minimize, resize, raise and change workspace together. Maximize a window to remove it from the group.", 
  "gettext-domain": "shelltile", 
  "name": "ShellTile", 
  "settings-schema": "org.gnome.shell.extensions.shelltile", 
  "shell-version": [
    "3.6", 
    "3.8", 
    "3.10", 
    "3.12", 
    "3.14", 
    "3.16",
    "3.18"
  ], 
  "url": "https://bitbucket.org/emasab/shelltile", 
  "uuid": "ShellTile@emasab.it", 
  "version": 30
}

Here are various checks/workarounds if it supports your version (it doesn't in this case but help others):

  • Reload the browser page.
  • Ensure the Gnome Shell Integration plugin is enabled (check about:plugins in Firefox)
  • Check whether the extension is enabled with Gnome Tweak Tool or here
  • If you have not previously installed the extension it should show something like: enter image description here If it is installed and working you there will be a preferences icon

  • It'll be installed if this folder exists:

    ~/.local/share/gnome-shell/extensions/ShellTile@emasab.it

  • Give up, report a bug:
