最终，维护者可能需要对 Python 包进行上游修补，因为 version/epoch 解析器显然认为前缀 -1+bionic1 比 -1ubuntu1.1 更新.
在我的例子中，Python 3.8 的 -1+bionic1 前缀来自从 deadsnakes PPA 安装 Python 3.8 包，而不是来自规范存储库。
就是说，我能够使用此命令将 "downgrade" 强制到正确的 Ubuntu-Focal 包：
sudo apt install libpython3.8:amd64=3.8.2-1ubuntu1.1 libpython3.8-dev:amd64=3.8.2-1ubuntu1.1 libpython3.8-minimal:amd64=3.8.2-1ubuntu1.1 libpython3.8-stdlib:amd64=3.8.2-1ubuntu1.1 python3.8=3.8.2-1ubuntu1.1 python3.8-minimal=3.8.2-1ubuntu1.1
我 运行 在 18.04->20.04 系统升级后尝试安装其他 Python 库，如 python3-venv，这些包将它们的依赖项固定到 3.8.2-1ubuntu1.1版本。
我在从 18.04 升级到 20.04 后安装 vim 时遇到了类似的问题。结合 pztrick answer 和 oon arfiandwi comment on accepted answer 对我有用
sudo apt install libpython3.8:amd64=3.8.2-1ubuntu1 libpython3.8-dev:amd64=3.8.2-1ubuntu1 libpython3.8-minimal:amd64=3.8.2-1ubuntu1 libpython3.8-stdlib:amd64=3.8.2-1ubuntu1 python3.8=3.8.2-1ubuntu1 python3.8-minimal=3.8.2-1ubuntu1
运行之后
apt --fix-broken install
我可以安装 vim.
