dpkg: error processing archive /var/cache/apt/archives/libpython3.7-stdlib_3.7.3-2~18.04.1_amd64.deb

使用 apt update 和 apt upgrade 遇到error 被中斷，系統提示需要我下這行指令：apt –fix-broken install，執行結果還是被中斷

發生的原因是因為我在系統上已經安裝了 python 3.7.3 所以蓋不過去的樣子。解法，下指令：

sudo dpkg --install --force all /var/cache/apt/archives/libpython3.7-stdlib_3.7.3-2~18.04.1_amd64.deb

先使用 sudo dpkg –install –force all 把被中斷的 deb 強制執行，系統會彈出提示視窗，問在覆蓋系統檔案時，如果有重開機的需求時，要不要自動幫使用者重開機。
