当试图在virt-manager中创建或打开VM时，获取错误“libosinfo:意外的文件类型(0)”

Question

在virtual中单击“Open”或“Create a new虚拟机”时会出现以下错误：

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

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/vmwindow.py", line 39, in get_instance
    cls._instances[key] = vmmVMWindow(vm)
  File "/usr/share/virt-manager/virtManager/vmwindow.py", line 76, in __init__
    self._details = vmmDetails(self.vm, self.builder, self.topwin,
  File "/usr/share/virt-manager/virtManager/details/details.py", line 447, in __init__
    self.init_details()

    self._init_state()

    all_os = virtinst.OSDB.list_os()

    for name, osobj in self._all_variants.items():
  File "/usr/share/virt-manager/virtinst/osdict.py", line 198, in _all_variants
    loader = self._os_loader
  File "/usr/share/virt-manager/virtinst/osdict.py", line 190, in _os_loader
    loader.process_default_path()
gi.repository.GLib.GError: libosinfo: Unexpected file type (0)

这是我从Ubuntu18.04升级到Ubuntu20.04之后开始的。

我怎样才能消除这个错误？

也有同样的问题。对“~/..config”的权限错误。将所有者设置为"user:user“，然后away...you可以通过运行”virt-调试“来检查是否存在拒绝权限的错误。
