I upgraded from 13.04 to 13.10 and now all icons in the application lens are gone.

Screenshot of missing applications in Unity 13.10 application lens

This is what I tried so far:

  • apt-get install --reinstall unity-lens-applications
  • unity --replace and unity --reset-icons
  • moving ~/.config to ~/.config2
  • deleting ~/.cache/software-center and ~/.cache/unity

Most of these things have been suggested in this question: Unity Applications lens is empty - but all to no avail.

I have the same problem and filled a bug report on Launchpad. – Frédéric Grosshans Oct 30 '13 at 12:02

I think this is likely because the unity-scope-home package is not installed.

Try using Software Center to find and install that package, log out and back in to restart Unity, and see if that resolves the problem.

Ran apt-get install unity-scope-home and all items are back again :) Thank you! – Michael Osl Nov 4 '13 at 9:41

I think I may have had a similar problem, not sure it was due to upgrading to 13.10 or due to user error. I ended up fixing it as follows:

  1. Log out of unity and log in to tty1 (ctrl-alt-f1).
  2. "sudo apt-get purge unity" (gets rid of unity and it's settings).
  3. "sudo apt-get autoremove" (gets rid of any leftover packages that unity depended on, like the lenses and such.)
  4. "sudo reboot" and log into tty1 again afterwards.
  5. "sudo apt-get install unity"

Bit drastic, but it worked.
