Unity Applications lens is empty
Solution 1:
In the terminal try
unity --reset
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.
Solution 2:
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.
Solution 3:
You can also use the command
unity --replace
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.
