这很可能是由于 15.04 及更高版本中出现的错误造成的，错误本身已报告给启动板，您可以在此处查看https://bugs.launchpad.net/ubuntu/+source/runit/+bug/1448164。
这是因为 runit 依赖于 upstart，而 Ubuntu 已决定在 15.04 中将 systemd 移至默认 init 系统。要消除错误，您需要清除runit、git& git-all：
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
