我是 Linux 管理活动的新手，对术语不太熟悉。我需要安装 python-pip。但是，它依赖于已安装但无法识别的 python-pip-whl (20.1.1-2 )。

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:
python-pip : Depends: python-pip-whl (= 9.0.1-2.3~ubuntu1.18.04.4) but 20.1.1-2 is to be installed
Recommends: python-setuptools but it is not going to be installed
Recommends: python-wheel but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
所以，我安装了 python-pip-whl (20.1.1-2 )。但是，我认为旧版本 python-pip-whl 的存在导致了这个问题。这种情况该如何处理。
