[virtualbox ubuntu] error processing package git-daemon-run

再安裝git時遇到這樣的問題

start: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: 連線被拒絕
dpkg: error processing package runit (--configure):
 子程序 已安裝的 post-installation script 傳回了錯誤退出狀態 1
dpkg: 因相依問題，無法設定 git-daemon-run：
 git-daemon-run 相依於 runit﹔然而：
  runit 套件尚未設定。

dpkg: error processing package git-daemon-run (--configure):
 相依問題 - 保留未設定

處理時發生錯誤：
 runit
 git-daemon-run
E: Sub-process /usr/bin/dpkg returned an error code (1)


看起來是套件出了一些問題

於是可以這樣做

sudo apt-get purge runit
sudo apt-get purge git-all
sudo apt-get purge git
sudo apt-get autoremove
sudo apt update
sudo apt install git

就能順利安裝了
