应用程序不会出现在Dash中(14.04)

Question

我运行14.04

我已经读过这个问题了，这个问题的答案大致和网络上的其他答案一样，对我不起作用。

所有应用程序都会在Dash中消失.

我可以在没有问题的情况下搜索所有其他文件，但是当我试图搜索应用程序时，我无法这样做。

我不知道如何解决这个问题--我已经确保安装了unity-lens-applications和unity-scope-master。

我还能做些什么来解决这个问题吗？老实说，我宁愿不用从终端启动我所有的应用程序。

在新创建的用户帐户上，应用程序确实会出现.但是，我想在我的登录上解决这个问题。

建议修正

• 在alt + unity中运行F2 --这将返回与上面相同的错误，减去过滤器。
• sudo apt-get install zeitgeist zeitgeist-core它已经安装并且是最新的

其他无效的建议：

• clear $HOME/.cache/和重新启动
• 如何重置我的统一配置？
• 如何将侏儒重置为默认值？
• 团结不装载，没有发射器，没有飞镖出现

Answer 1

实际上，登录客人会话，并重新登录作为主要用户刚刚解决了问题，因为我仍然不太明白为什么.但是在这样做之前，我花了时间尝试上面的命令行，这对我的情况没有任何积极的影响。当然，我们希望找到一种重新设置这些.desktop文件的方法，这显然是问题所在，甚至是一种清除它们的方法，以防它们被破坏。thx无论如何

Answer 2

请注意，在您的情况下，在类型或类别下没有Applications (对比请参见图)。在从14.04 LTS升级到16.04 LTS之后，我也遇到了同样的问题。对我有效的解决办法是

破折号(来自统一)没有显示应用程序)

我在这里复制答案：

sudo apt-get purge unity-lens-applications    
sudo apt-get install unity-lens-applications 

然后注销并登录。

Answer 3

如果它只涉及应用程序，但是其他文件可以在Dash中进行很好的研究，那么您可以尝试这样做，然后重新登录：

rm ~/.cache/software-center -R
