尝试在 virt-manager 中创建或打开虚拟机时出现错误“libosinfo：意外文件类型 (0)”

在 virt-manager 中单击“打开”或“创建新虚拟机”时出现以下错误：

Error launching details: libosinfo: Unexpected file type (0)

这是在我从 Ubuntu 18.04 升级到 Ubuntu 20.04 后开始的。

我怎样才能消除这个错误？

遇到了完全相同的问题。“~/.config”上的权限错误。将所有者设置为“user:user”，错误消失...您可以通过运行“virt-manager --debug”来检查是否存在权限被拒绝的错误
