升级到ubuntu 20.04后，某些软件包保留在+ bionic1版本中

如您在python3.8-minimal/now 3.8.2-1+bionic1 amd64 [installed,local]上所见，如果我要清除并安装python3.8，则仍处于仿生版本，那么许多依赖关系也将被删除，这可能会导致操作系统中断，我该如何按ubuntu切换所有安装+ bionic1软件包到焦点版本ubuntu1.1或ubuntu1
答案 0 :(得分：3)
最终，维护者可能需要对Python软件包进行上游修补，因为版本/时代分析器显然认为前缀-1+bionic1比-1ubuntu1.1更新。
在我的情况下，Python 3.8的-1+bionic1前缀来自从deadsnakes PPA而非标准存储库安装Python 3.8软件包。
也就是说，我能够使用以下命令将“降级”强制为正确的Ubuntu-Focal软件包：
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
在18.04-> 20.04系统升级后，我尝试安装其他Python库（例如python3-venv）时遇到了这个问题，这些软件包将其依赖项固定为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 答案和 oon arfiandwi 对已接受答案的评论对我有用
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
答案 2 :(得分：0)
运行后
apt --fix-broken install
我可以安装vim。
