Ubuntu – Applications don’t appear in the Dash (14.04)

14.04unity-dash

I'm running 14.04

Applications Dash

I've had a read through this question, which has an answer which is roughly along the lines of other answers on the web, and doesn't work for me.

All Applications Disappear in the Dash

I can search all other files without an issue, but when I attempt to search for Applications, I'm not able to do so.

I'm not sure where to go with troubleshooting this – I've ensured that unity-lens-applications is installed, along with unity-scope-master.

Is there anything else I can do to fix this? I'd honestly prefer not to have to launch all my applications from a Terminal.

On a newly-created user account, applications do appear. However, I'd like to get this fixed on my login.

Suggested fixes

  • Run unity in alt + F2
    This returns the same error as above, less the filters.
  • sudo apt-get install zeitgeist zeitgeist-core
    It was already installed and up to date

Other suggestions which were ineffective:

Best Answer

As it is only constrained to your user account, it must have something to do with your user.

Maybe one of the .desktop files in your home folder is tripping the launcher up? Can you try moving the files in these folders all somewhere else:

  • /home/<youruser>/.gnome/apps/
  • /home/<youruser>/.local/usr/share/applications/

e.g.

$ mkdir backup_local
$ mkdir backup_gnome
$ mv .local/share/applications/*.desktop backup_local/
$ mv .gnome/apps/*.desktop backup_gnome/

Then logout, login and see if it changed anything? You can always move them back in if it didn't help. If it did help, try moving them in one by one to which file was the culprit.

EDIT: You can find out which one was malformed:

  1. Install the desktop-file-utils package:

    sudo apt-get install desktop-file-utils

  2. Check each of the .desktop files for validity using desktop-file-validate:

    desktop-file-validate .local/share/applications/*.desktop
desktop-file-validate .gnome/apps/*.desktop

    Or of course at the different location if you already moved it. It will print nothing if all files are OK. If any of the files are malformed, it will print one error message per line.

    You might also want to check the other desktop files for good measure:

    desktop-file-validate /usr/share/applications/*.desktop
