UPDATE: What outlined below did not work, so here is what I ended up doing:<\/p>\n
Change directory to:<\/p>\n
$ cd \/etc\/apt\/apt.conf.d<\/p><\/blockquote>\n
Edit the 20auto-upgrades, and change the Lists setting from 1 to 0:<\/p>\n
$ sudo vi 20auto-upgrades
\nAPT::Periodic::Update-Package-Lists “0”;
\nAPT::Periodic::Unattended-Upgrade “1”;<\/p><\/blockquote>\nNow, with the list disabled the service should never find anything to update.<\/p>\n
Another option is just get rid of the service:<\/p>\n
$ sudo apt remove unattended-upgrades<\/p><\/blockquote>\n
Note: The following did not work in Ubuntu 18.x:<\/p>\n
For reason, I don’t know if this an Azure deployment issue or an Ubuntu decision, but I have found automatic updates turned on by default in a couple VMs. Not sure why you would ever want your production server automatically updating, so:<\/p>\n
Check to status of the unattended-upgrades service:<\/p>\n
$ sudo systemctl status unattended-upgrades<\/p><\/blockquote>\n
Stop the service:<\/p>\n
$ sudo systemctl stop unattended-upgrades<\/p><\/blockquote>\n
Disable the service. NOTE: Services that have this as a dependency will start the service despite it being disabled. I am not aware of any for this service, but just putting it out there.<\/p>\n
$ sudo systemctl disable unattended-upgrades<\/p><\/blockquote>\n
To prevent the unintended situation above, mask will create a link to \/dev\/null to prevent the service from being started whether there are dependencies or not.<\/p>\n
$ sudo systemctl mask unattended-upgrades<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
