[Ubuntu 22.04.2] Running kernel seems to be up-to-date. Restarting services Daemons using outdated

1. 问题现象

  安装ubuntu 22.04.2版本后，安装软件时，总是提示：Running kernel seems to be up-to-date. Restarting services... Daemons using outdated libraries

Restarting services...
Daemons using outdated libraries
--------------------------------

  1. networkd-dispatcher.service  2. unattended-upgrades.service

(Enter the items or ranges you want to select,separated by spaces.)

Which services should be restarted?

2. 问题分析

  根据因为提示，大致意思是说本地安装的networkd-dispatcher.service,unattended-upgrades.service这两个服务版本太旧，问我们是否需要更新这两个服务。（其实潜台词就是我们再安装程序的时候，ubuntu自动下载了这连个服务的新版本）

  这种设计确实还是有点烦人的，特别是再执行脚本的时候，如果还有这种交互流程，那就非常不方便了。

  网上搜索了一下，主要看来有三种解决方案：1、自动重启服务 2、列出需要重启的服务，用户自行决定是否需要重新服务 3、删除每次通过apt/apt-get安装软件时自动更新程序

3. 解决方案

  这三种解决方案，选择其中的一种即可，不需要都设置。

3.1. 每次自动重启更新的服务

sudo sed -i 's/#$nrconf{restart} = '"'"'i'"'"';/$nrconf{restart} = '"'"'a'"'"';/g' /etc/needrestart/needrestart.conf

3.2. 列出自动更新的服务，由用户自行决定是否需要重启服务

sudo sed -i 's/#$nrconf{restart} = '"'"'i'"'"';/$nrconf{restart} = '"'"'l'"'"';/g' /etc/needrestart/needrestart.conf

3.3. 移除自动更新服务的程序

sudo apt-get remove needrestart
