Newer #fwupd versions take the redirect from the LVFS and download firmware from the CDN, but older (and unsupported) fwupd clients don't handle the client-side redirect, so we just deliver the content directly.

It's expensive to supply firmware without the CDN. This mainly affects Debian, which never uprevs fwupd, which means lots of devices are missing firmware updates.

Unsupported fwupd versions download ~6% of all firmware updates but account for over 40% of the daily bandwidth. Ideas?

@hughsie I am assuming that this issue you have is with debian stable (bullseye) right?

There is going to be a new Debian release in the next few months. The freeze of the testing version is starting now, to prepare a new debian release.

Won't your problem solve it self out this quarter with the release of the next debian version?

@joao bullseye has 1.5.7 which isn't even the latest version from the 1.5.X branch -- but that's not my problem. Debian *stretch* users are downloading updates.

@hughsie just as a nitpick; Bookworm has. 1.8.8-1

But your answer gives more context to your problem. It was that missing that part, that you where referring to stretch users.
