lsb发布与python3之间的循环依赖关系(ubuntu18.04)

Question

我设法进入了一种情况，在lsb发布和python3之间存在循环依赖关系。当我尝试sudo apt install python3 --reinstall时，我得到以下内容(只是粘贴键行)

(Reading database ... 470097 files and directories currently installed.)
Preparing to unpack .../python3_3.6.7-1~18.04_amd64.deb ...
Could not find platform independent libraries 
Could not find platform dependent libraries

[~] lsb_release

显然我的lsb_release坏了。但如果我运行sudo apt-get install lsb-release

dpkg: error processing package python3 (--configure):
 package is in a very bad inconsistent state; you should
 reinstall it before attempting configuration
dpkg: dependency problems prevent configuration of lsb-release:
 lsb-release depends on python3:any (>= 3.4~); however:
  Package python3 is not configured yet.

因此，如果不修复lsb版本，我就无法修复我的python3安装，反之亦然。

您可以在不修复lsb_release的情况下修复Python安装。您的Python安装需要重新安装其他Python包；至少

sudo apt install --reinstall libpython3.6-minimal

也许还有更多。若要重新安装所有软件包，请运行

sudo apt install --reinstall libpython3.6{,-minimal,-stdlib} python3.6{,-minimal}

然后，您会发现lsb_release工作得很好。
