50unattended-update entry confusion (for me anyway)

In the 50unattended-update file the entries look like this
// Automatically upgrade packages from these (origin:archive) pairs
Unattended-Upgrade::Allowed-Origins {
// “${distro_id}:${distro_codename}-updates”;
// “${distro_id}:${distro_codename}-proposed”;
// “${distro_id}:${distro_codename}-backports”;

My question is regarding the first entry: “${distro_id}:${distro_codename}”;
What does it mean? The other entries all make sense to me because they specify what is to be updated, but this entry does not. It “feels” like it might mean to update everything…

This site is for the co-ordination of the Ubuntu project(s), and not support.

For Ubuntu Support options, there are many listed at https://community.ubuntu.com/t/finding-help/712

The short answer to your question is that those are repositories, not packages.

Note that the only repository enabled by default is -security. Generally, you want to upgrade everything in there anyway.

The Ubuntu Wiki has some great pages that explain what repositories are and how they work.

I’ve moved this to the https://community.ubuntu.com/c/support-help-requests category because this site isn’t designed to take tech support questions. Sorry. I’d recommend using one of the official support channels listed on the https://community.ubuntu.com/t/finding-help/712 page.
