Ubuntu软件没有显示任何软件

Question

安装16.04后，Ubuntu软件总是空的，如屏幕截图所示。我怎么才能解决这个问题？

Answer 1

在软件和更新中更改从服务器下载的内容。我把我的照片放在了附近的一个瑞典手机上(也许它本身还没有更新)。我换了一个更正式的英国服务器，Ubuntu软件现在正在工作。

Answer 2

如果sudo apt-get update && sudo apt-get upgrade后面的重新启动不能解决这个问题，我建议：

sudo apt-get dist-upgrade

重新启动。如果这没有帮助，您也可以尝试备份，然后删除与程序相关的主目录中的文件夹。首先，在终端或其他CLI中：

killall gnome-software

然后

mv ~/.local/share/gnome-software{,-BAK}

重新打开Ubuntu软件。(如果需要，您可以随时撤消gnome软件文件夹的删除，并恢复备份：rm -r ~/.local/share/gnome-software && mv ~/.local/share/gnome-software{-BAK,})

最后，如果所有这些都不适合您，我想知道以下内容的输出：

find /etc/apt/ -name '*.list' -ls -exec cat {} \;

这是所有允许的源的列表(源代码是包含可下载软件的存储库)。

虽然我想不出为什么您在sources.list中什么都没有，但这也是我唯一能想到的解释，为什么在Ubuntu中，在尝试了所有正常的故障排除步骤之后，什么都没有出现。

在上面的示例中，启用了四个主要存储库。

1. 主要规范支持的免费和开放源码软件。
2. 宇宙-社区维护自由和开放源码软件。
3. 设备专用驱动程序。
4. 多重-受版权或法律问题限制的软件。

还启用了更新。没有启用来自规范合作伙伴的软件的Repos。这些是第一次安装Ubuntu时启用的标准选项。

如果您添加了任何PPA，它们也会出现在上面的输出中。

Answer 3

如果上面的方法不起作用，试着重新安装Gnome-软件，这对我是有效的。

sudo apt autoremove gnome-software && sudo apt install gnome-software
