Why APT::Periodic variables are set in two files?





.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}

...namely in /etc/apt/apt.conf.d/10periodic and /etc/apt/apt.conf.d/20auto-upgrades.



$ dpkg-query -S /etc/apt/apt.conf.d/10periodic
update-notifier-common: /etc/apt/apt.conf.d/10periodic

$ dpkg-query -S /etc/apt/apt.conf.d/20auto-upgrades

  • 20auto-upgrades is generated by dpkg-reconfigure for Unattended Upgrades instead of installed directly. Source: bazaar.launchpad.net/~unattended-upgrades-developers/…. Since each of the two files comes from a different package, using separate files makes installation and removal simpler.

  • @user535733 the documentation is old; github.com/mvo5/unattended-upgrades/blob/master/README.md seems to be more up-to-date, but I am not sure, if it is the official one. dpkg-reconfigure may modify 20auto-upgrades, but if I delete the file, it will not change the configuration.
