Well it's the letter "L". Anyways I guess your ".wazapp" folder is already gone. You can check if it exists if you try to recreate it with Code: mkdir /home/user/.wazapp If it does not throw an error, your folder was gone before. If it throws an error however, your .wazapp folder is still there. In that case try again to delete it.
mkdir /home/user/.wazapp
