16.04 Gnome 软件中心无法打开。当我单击启动器上的图标时，它只会显示加载图标，仅此而已。
我查了一下，什么都不起作用。我什么也没做，就是打不开。这是今天新安装的。当它工作正常时，我首先点击了“尝试 Ubuntu”选项，它会打开，但由于我实际安装了它，所以它不会打开。
在终端输入后apt policy software-center gnome-center，我得到了这个：
software-center:

打字后software-center，它给了我
The program 'software-center' is currently not installed. You can install it by typing:
sudo apt install software-center
输入之后gnome-software，没有显示任何内容。
输出gnome-software --verbose如下：

有人能帮帮我吗？谢谢。

可以通过删除文件 来解决此问题~/.local/share/gnome-software。启动 gnome-software 时将重新创建该文件。因此，请确保您没有正在运行的ubuntu-software或实例gnome-software：
$ killall ubuntu-software
$ killall gnome-software
进而：
$ rm -r ~/.local/share/gnome-software
