我正在编写自己的Distro层（以及我自己的图像配方），但是在尝试构建图像时却不断出现此错误：
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
packagegroup-base-extended : Depends: packagegroup-base but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
如何解决此问题？
请确保将软件包组包括在映像配方中，而不是发行版配置。
