Short story: I think unity-lens-applications should Depend (not Recommend or Suggest) zeitgeist OR zeitgeist-core for installation. On some system the zeitgeist daemon may not be installed, thus causing the lens to malfunction.
Long story: I have configured APT to prevent installation of soft-dependencies (Recommended and Suggested dependencies) like this: APT::Install-Recommends "0"; APT::Install-Suggests "0"; Apt::AutoRemove::RecommendsImportant "0"; Apt::AutoRemove::SuggestsImportant "0"; Now, unity-lens-applications depends on libzeitgeist which in turn Recommends zeitgeist OR zeitgeist-core. Since it is a Recommended package it is not installed on my system, thus the zeitgeist daemon is not started. I had to manually install at least zeitgeist-core, then restart unity- applications-daemon to have it spawn the zeitgeist daemon. After that, the lens worked as before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/964146 Title: [workaround] Application lens is empty since the update to 5.8.0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity-lens-applications/+bug/964146/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
