查看此 github 评论及其正下方的评论（用于复制可粘贴脚本），了解一些对我有用的解决方案。

为了方便任何人访问，这里是评论的重要文本（如果可以的话，你应该给 github 评论上的人点赞）：

（我必须在运行sudo -s或在每行前面加上前缀后执行此操作sudo）

cat > /usr/sbin/policy-rc.d <<EOF
#!/bin/sh
exit 101

chmod +x /usr/sbin/policy-rc.d
dpkg-divert --local --rename --add /sbin/initctl
ln -s /bin/true /sbin/initctl
