Nothing like a good Geeky command after the Yom Kippur 25 hour fast! Ubuntu loves to run apt-daily.service on Startup, which messes with devops pre-installations. In My case I want to run docker-machine.
Turn off auto updates
edit file 20-auto-upgrades in /usr/share/unattended-upgrades
Turn the service back on after 20 minutes
or /etc/apt/apt.conf.d

So the plan is to run a cron job that runs during startup that kills apt-daily.service.

@weekly : Run once a week, ie. “0 0 * * 0”.
@daily : Run once a day, ie. “0 0 * * *”.
@hourly : Run once an hour, ie. “0 * * * *”.CAVEATS
In this version of cron , /etc/crontab must not be writable by any user
other than root. No crontab files may be links, or linked to by any
other file. No crontab files may be executable, or be writable by any
user other than their owner.

383 down vote One approach is to add an @reboot cron task: Running crontab -e will allow you to edit your cron. Adding a line like this to it: @reboot /path/to/script will execute that script once your computer boots up.
