只要执行 sudo apt install xxx 或者 sudo apt upgrade 之后都会显示下面的弹窗：
Daemons using outdated libraries
我也不知道勾选哪个？
直接点确定，就变成了这样！
Scanning processes...
Scanning candidates...
Scanning linux images...
Running kernel seems to be up-to-date.
Restarting services...
systemctl restart cron.service ssh.service systemd-journald.service
Service restarts being deferred:
systemctl restart NetworkManager.service
/etc/needrestart/restart.d/dbus.service
systemctl restart lightdm.service
systemctl restart systemd-logind.service
systemctl restart user@1000.service
systemctl restart user@131.service
No containers need to be restarted.
No user sessions are running outdated binaries.特别烦人！！！
