How would we know what a new release is?

[rahulsundaram]

Is there no automated mechanism which tracks presence of new releases in Fedora anymore? I was only aware of https://mirrors.fedoraproject.org/releases.txt which has since become obsolete

[Conan-Kudo]

As far as I know, no. I never integrated support for system-upgrade into dnfdaemon because I don't know how to actually identify valid upcoming releases.

How does tools like GNOME Software do it?

[Conan-Kudo]

I'm not sure. I use KDE, so I never really used it. Unfortunately, Plasma Discover doesn't support this either. :(

As far as I know, only GNOME Software supports it.

Currently gnome-software uses https://github.com/GNOME/gnome-software/tree/master/plugins/fedora-pkgdb-collections which checks https://admin.fedoraproject.org/pkgdb/api/collections

[rahulsundaram]

So now that we know that there is an API available, can upgrade support be added?

[Conan-Kudo]

Yeah, I can look into this. I'll need to figure out how to emulate the system-upgrade mechanism...

While I'd love to have this feature, a simple notification would already be a great improvement. I thought about something like:

• There is a newer release of Fedora available. To upgrade follow directions on https://fedoraproject.org/wiki/DNF_system_upgrade
• This Fedora release has reached EOL. It doesn't receive any updates any more, including security fixes. It's strongly suggested to upgrade to a supported release of Fedora, following directions onhttps://fedoraproject.org/wiki/DNF_system_upgrade

I could support by translating necessary messages to German

Really needed this feature if added will make dnfdragora better ...

[Conan-Kudo]

My understanding is that the API that GNOME Software uses now is deprecated and there is supposed to be a replacement for it. Also, we'd probably need to define an interface that multiple distributions can implement...
