Ubuntu软件没有显示任何软件

安装16.04后,Ubuntu软件始终为空,如屏幕截图所示。 我怎样才能解决这个问题?

在此处输入图像描述

在“ 软件和更新”中更改“ 服务器下载 。 我有一个附近的瑞典人(可能本身还没有更新)。 我改为更正式的英国服务器,Ubuntu软件正在运行。

这很可能是因为新安装的系统缺少可用软件包的数据库。 您可以使用以下步骤从包存储库生成最近的一个。

  1. 打开终端。 有很多方法可以实现这一目标,但最常见的是

    • 在短划线中键入terminal并启动相同名称的应用程序或
    • Ctrl + Alt + T.
  2. 键入或复制并粘贴以下命令到终端运行它们:

     sudo apt update sudo apt upgrade -y 

    (如果您在此过程中遇到任何错误,请打开一个新问题,并逐字包含这些命令的全部输出。)

  3. 重新打开软件中心,然后重试。

如果sudo apt-get update && sudo apt-get upgrade然后重启并不能解决问题,我建议:

 sudo apt-get dist-upgrade 

重新开始。 如果这没有帮助,您还可以尝试备份,然后删除与该程序关联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,您可以随时撤消删除gnome-software文件夹并恢复备份: rm -r ~/.local/share/gnome-software && mv ~/.local/share/gnome-software{-BAK,}

最后,如果这些都不适合你,我很想知道输出:

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

这是所有允许的源列表(源是包含可下载软件的存储库)。

虽然我想不出你为什么在sources.list中没有任何东西的任何理由,但这也是我能想到的唯一解释,为什么在尝试所有正常的故障排除步骤之后,Ubuntu软件中没有任何东西显示出来。

上述命令的输出示例:

在上面的示例中,启用了四个主存储库。

  1. Main – Canonical支持的免费和开源软件。
  2. Universe – 社区维护的免费和开源软件。
  3. 受限制 – 设备的专有驱动程序。
  4. Multiverse – 受版权或法律问题限制的软件。

更新也已启用。 未启用Canonical合作伙伴软件的Repos。 这些代表了首次安装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。
