Slow Ubuntu startup time due to apt-daily.service

The     apt-daily.service   makes users feel very slow when running at startup. There is a workaround to delay its execution after system boot up: Do the following:  sudo systemctl edit apt-daily.timer  And paste the config to the config file:  # apt-daily timer configuration override   [Timer]   OnBootSec=15min   OnUnitActiveSec=1d   AccuracySec=1h   RandomizedDelaySec=30min  References: https://askubuntu.com/questions/800479/ubuntu-16-04-slow-boot-apt-daily-service https://ubuntu-mate.community/t/shorten-boot-time-apt-daily-service/12297
