The accept answer states:
Most of the answer is in your unattended-upgrades logfile, located at
Here’s an example:
2018-01-08 06:17:51,770 INFO Starting unattended upgrades script 2018-01-08 06:17:51,771 INFO Allowed origins are: ['o=Ubuntu,a=xenial-security'] 2018-01-08 06:18:07,765 INFO No packages found that can be upgraded unattended and no pending auto-removals
Take a look at that middle line ‘Allowed origins’. That means Software
Repositories. The only source there is -security. Not -upgrades, not
-backports, no PPAs, no third-party repos.
In other words, this example unattended-upgrades is only providing
security upgrades. Nothing else.
You can add, remove, or edit Allowed Origins (repositories) through
the Software and Updates Control Panel, or by editing the
unattended-upgrades config file, located at
The rest of the answer is that Xenial (16.04) is two years old. Fewer
new security updates for old software.
