我是 Ubuntu 新手，在全新安装 Ubuntu 22.04 后，我发现无法通过以下方式安装任何程序Ubuntu 软件，然后我安装了软件（gnome-software）并尝试了一下，但面临同样的问题：
当我打开软件应用程序并点击任何应用程序尝试安装，之后软件应用程序自动关闭。
然后我尝试启动软件使用以下命令通过终端运行应用程序：
gnome-software
选择任何应用程序并重复相同的步骤，单击该应用程序后，终端显示以下错误：

我尝试更新和升级软件包，重新安装 gnome 软件，但它仍然关闭，请帮我解决这个问题
答案1
Ubuntu Software 在后台使用的 Snapcraft 今天由于防火墙问题而出现间歇性中断。您可以看到它在尝试访问时如何出现 HTTP 500 错误（服务器错误）api.snapcraft.io。
你什么也做不了，因为问题出在他们的服务器上。它应该很快就能恢复运行（希望如此）。
答案2
运行以下命令：
rm ~/.local/share/gnome-software/*
sudo apt-get upgrade gnome-software
sudo apt-get update
我希望这能解决问题。
如果这对您有用，请评论。
