How do I enable unattended-upgrades for stable versions of all packages (regardless of repository) in Ubuntu 19.04?

Question

Just wondering how I do the above. This is what my /etc/apt/apt.conf.d/50unattended-upgrades currently looks like:

// Automatically upgrade packages from these (origin:archive) pairs
//
// Note that in Ubuntu security updates may pull in new dependencies
// from non-security sources (e.g. chromium). By allowing the release
// pocket these get automatically pulled in.
Unattended-Upgrade::Allowed-Origins {
    "${distro_id}:${distro_codename}";
    "${distro_id}:${distro_codename}-security";
    // Extended Security Maintenance; doesn't necessarily exist for
    // every release and this system may not have it installed, but if
    // available, the policy for updates is such that unattended-upgrades
    // should also install from here by default.
//  "${distro_id}ESM:${distro_codename}";
    "${distro_id}:${distro_codename}-updates";
//  "${distro_id}:${distro_codename}-proposed";
//  "${distro_id}:${distro_codename}-backports";
};

// Python regular expressions, matching packages to exclude from upgrading
Unattended-Upgrade::Package-Blacklist {
    // The following matches all packages starting with linux-
//  "linux-";

    // Use $ to explicitely define the end of a package name. Without
    // the $, "libc6" would match all of them.
//  "libc6$";
//  "libc6-dev$";
//  "libc6-i686$";

    // Special characters need escaping
//  "libstdc\+\+6$";

    // The following matches packages like xen-system-amd64, xen-utils-4.1,
    // xenstore-utils and libxenstore3.0
//  "(lib)?xen(store)?";

    // For more information about Python regular expressions, see
    // https://docs.python.org/3/howto/regex.html
};

// This option controls whether the development release of Ubuntu will be
// upgraded automatically. Valid values are "true", "false", and "auto".
Unattended-Upgrade::DevRelease "auto";

// This option allows you to control if on a unclean dpkg exit
// unattended-upgrades will automatically run 
//   dpkg --force-confold --configure -a
// The default is true, to ensure updates keep getting installed
//Unattended-Upgrade::AutoFixInterruptedDpkg "true";

// Split the upgrade into the smallest possible chunks so that
// they can be interrupted with SIGTERM. This makes the upgrade
// a bit slower but it has the benefit that shutdown while a upgrade
// is running is possible (with a small delay)
//Unattended-Upgrade::MinimalSteps "true";

// Install all updates when the machine is shutting down
// instead of doing it in the background while the machine is running.
// This will (obviously) make shutdown slower.
// Unattended-upgrades increases logind's InhibitDelayMaxSec to 30s.
// This allows more time for unattended-upgrades to shut down gracefully
// or even install a few packages in InstallOnShutdown mode, but is still a
// big step back from the 30 minutes allowed for InstallOnShutdown previously.
// Users enabling InstallOnShutdown mode are advised to increase
// InhibitDelayMaxSec even further, possibly to 30 minutes.
//Unattended-Upgrade::InstallOnShutdown "false";

// Send email to this address for problems or packages upgrades
// If empty or unset then no email is sent, make sure that you
// have a working mail setup on your system. A package that provides
// 'mailx' must be installed. E.g. "user@example.com"
  Unattended-Upgrade::Mail "redacted";

// Set this value to "true" to get emails only on errors. Default
// is to always send a mail if Unattended-Upgrade::Mail is set
  Unattended-Upgrade::MailOnlyOnError "true";

// Remove unused automatically installed kernel-related packages
// (kernel images, kernel headers and kernel version locked tools).
  Unattended-Upgrade::Remove-Unused-Kernel-Packages "true";

// Do automatic removal of newly unused dependencies after the upgrade
  Unattended-Upgrade::Remove-New-Unused-Dependencies "true";

// Do automatic removal of unused packages after the upgrade
// (equivalent to apt-get autoremove)
  Unattended-Upgrade::Remove-Unused-Dependencies "true";

// Automatically reboot *WITHOUT CONFIRMATION* if
//  the file /var/run/reboot-required is found after the upgrade
  Unattended-Upgrade::Automatic-Reboot "true";

// Automatically reboot even if there are users currently logged in
// when Unattended-Upgrade::Automatic-Reboot is set to true
  Unattended-Upgrade::Automatic-Reboot-WithUsers "true";

// If automatic reboot is enabled and needed, reboot at the specific
// time instead of immediately
//  Default: "now"
//Unattended-Upgrade::Automatic-Reboot-Time "02:00";

// Use apt bandwidth limit feature, this example limits the download
// speed to 70kb/sec
//Acquire::http::Dl-Limit "70";

// Enable logging to syslog. Default is False
   Unattended-Upgrade::SyslogEnable "true";

// Specify syslog facility. Default is daemon
// Unattended-Upgrade::SyslogFacility "daemon";

// Download and install upgrades only on AC power
// (i.e. skip or gracefully stop updates on battery)
   Unattended-Upgrade::OnlyOnACPower "true";

// Download and install upgrades only on non-metered connection
// (i.e. skip or gracefully stop updates on a metered connection)
   Unattended-Upgrade::Skip-Updates-On-Metered-Connections "true";

// Verbose logging
   Unattended-Upgrade::Verbose "true";

// Print debugging information both in unattended-upgrades and
// in unattended-upgrade-shutdown
   Unattended-Upgrade::Debug "true";

EDIT: I have far too many sources to list them all here, but an example of one line from them is:

deb [arch=amd64] http://repository.veeam.com/backup/linux/agent/dpkg/debian/public stable veeam

Would simply adding that string to the Unattended-Upgrade::Allowed-Origins list enable unattended upgrades for that package?

Btw, a much more thorough discussion on the subject is given in this answer

From https://github.com/mvo5/unattended-upgrades/blob/master/README.md#setup :

Allowed-Origins is a simple list of patterns of the form "<origin>:<archive>";.

... and exactly what to substitute for <origin> and <archive> could be deduced from the respective o=... and a=... output of:

sudo apt-cache policy | grep 'o=[^,]*.a=[^,]*'

eg.

release           o=jenkins.io ,a=binary           ,c=
release           o=Docker     ,a=xenial           ,l=Docker CE,c=stable,b=amd64
release v=16.04,  o=Ubuntu     ,a=xenial-security  ,n=xenial,l=Ubuntu,c=universe,b=amd64
release v=16.04,  o=Ubuntu     ,a=xenial-security  ,n=xenial,l=Ubuntu,c=main,b=amd64
release v=16.04,  o=Ubuntu     ,a=xenial-updates   ,n=xenial,l=Ubuntu,c=universe,b=amd64
release v=16.04,  o=Ubuntu     ,a=xenial-updates   ,n=xenial,l=Ubuntu,c=main,b=amd64
release v=16.04,  o=Ubuntu     ,a=xenial           ,n=xenial,l=Ubuntu,c=universe,b=amd64
release v=16.04,  o=Ubuntu     ,a=xenial           ,n=xenial,l=Ubuntu,c=main,b=amd64

(whitespace added to simulate grep's output highlighting)

The takeaway from this is that if you would add "*:*"; into the Unattended-Upgrade::Allowed-Origins { ... } list, then all (subject to their priority) sources listed by sudo apt-cache policy will be subjected to unattended upgrading.
