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?
Here is Solutions:
We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.
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.
You can also use the command
and you don’t need to reboot (more convenient). This command restart both Unity and Compiz and clean all the GUI like if she was restarted.
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
Note: Use and implement solution 1 because this method fully tested our system.
Thank you 🙂
