lsb-release 和 python3 (ubuntu 18.04) 之間的循環依賴

我已經設法陷入了 lsb-release 和 python3 之間存在循環依賴關係的情況。當我嘗試時，sudo apt install python3 --reinstall我得到以下資訊（只是粘貼關鍵行）

(Reading database ... 470097 files and directories currently installed.)

顯然我的 lsb_release 壞了。但是如果我跑sudo apt-get install lsb-release我會得到

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.

所以我不能在不修復 lsb-release 的情況下修復我的 python3 安裝，反之亦然。

您可以修復 Python 安裝而不修復lsb_release. 您的 Python 安裝需要重新安裝其他 Python 包；至少

sudo apt install --reinstall libpython3.6-minimal

也許更多。要重新安裝所有軟體包，請執行

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

然後，您應該會發現lsb_release效果很好。
