I am using Unity on Ubuntu 12.04. For some time now, the Applications lens is completely empty when I open it. If I search for any applications from the Home or Applications lens, no results show up. I have tried killing and launching the Applications lens as suggested at Launchpad, but it did not work. How can I get the applications lens to work again?
In the terminal try
and reboot to see the changes.
As far as the mentioned bug is concerned ,it was affecting the
unity-lens-applications-5.8.0-0ubuntu1 (precise) package and current version stands at
unity-lens-applications (5.12.0-0ubuntu1) .
It also states that
fix is released so please update your system , if already up-to-date than ignore this.
I know this has been fixed for the OP, but I had the same problem and it wasn't solved with the suggestions above. In the end I fixed with:
rm -r ~/.cache/unity && unity --replace &
My software centre was also broken and that was fixed with:
rm -r ~/.cache/software-center
From other posts I think the two may be connected hence posting both solutions together here for future searchers.
I am not sure but I think at least one of the previous fixes changes unity settings, setting them to default settings. This may be necessary, but sometimes just a restart of unity has worked for me. From another askubuntu site I found that typing the following in a terminal will restart unity and recover my lenses:
unity &> /dev/null & disown
