ubuntu-advantage-tools will adopt the deb822 format to comply with this spec, starting in version 31 - which will land in 24.04 and backported to 16.04+
Living status notes for noble:
- ubuntu-release-upgrader:
Updates to noble switch to ubuntu.sources - curtin: (AFACT)
- livecd-rootfs:
WIP
Following up from the Calamares side of things:
- Tweaked our automirror module to match the de facto standard thus far.
- Provided my two cents on the livecd-rootfs MP after some thought. I think this is a great start, just might need some minor tweaks on wording.
Also, let me just get this straight… so we have livecd-rootfs, curtin, and calamares all creating their own ubuntu.sources file at this point. When should we actually just make this into a common tool and switch all three to use it? 
Thanks!
Updates to noble switch to ubuntu.sources? but installing fro ISO dated 2024-01-18 I still see the old sources.list
Well yes, that’s what the status doc says. If you upgrade from an old release to noble, you get deb822 sources, but you don’t get any in the images just yet, the livecd-rootfs change is still pending.
And upgrading Noble installed from an old ISO? EG my ISO dated 2024-01-18 ?

@juliank I just upgraded to noble and lost a bunch of apt sources entries as (I am guessing) ubuntu-release-upgrader only upgraded one lot of entries from an old sources.list file into the new format - should I file a bug against u-r-u?
Yes please file a bug!
Installed from ISO dated 2024-02-15. software-properties-gtk does not start
Yes that’s a duplicate of Bug #2053165 “[noble] Version 2.7.5 causes software-properties t...” : Bugs : python-apt package : Ubuntu
You should be able to mark a bug as a duplicate of another.

FYI I did revert to this one:
https://launchpad.net/ubuntu/+source/python-apt/2.7.1~ubuntu1/+build/27047450/+files/python3-apt_2.7.1~ubuntu1_amd64.deb
(I do use old sources format).

gtk works perfectly now after downgrading python with the provided deb file! Thanks mate!
New here and to Linux. Seeing this after ignoring the python issue for a long time. I ignorantly upgraded to the dev branch of Ubuntu 24.04 from Ubuntu 22.04 LTS as a result of trying out do-release-upgrade blindly. (I didn’t bother to look up the -d flag and what it does.)
I avoided the software-properties-gtk python issue by deleting the older source files/entries from the /etc/apt/ folder as recommended by some in the LaunchPad Bug Report #2053228 linked above.
After Software & Updates started up again: out of all the repositories I did want to add, only AnyDesk’s one worked. Not only did the rest not work but those caused the app to crash. I had to manually remove the new entries/files from the /etc/apt/ folder again in order to continue opening it directly.
Glad to see that it has some solution but I’ll be avoiding it for now since the vulnerability in XZ Utils is still being cleaned up. There’s a long way to go.
Will this be completed by Noble release?
the latest daily builds (4/20/2024) still have the wrong sources.list and no ubuntu.sources file
eg:
https://cdimage.ubuntu.com/daily-preinstalled/pending/noble-preinstalled-desktop-arm64+raspi.img.xz
sources.list
# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.

Thanks for bringing this to our attention. Along with some other reports of issues, this made us realize the images were still being built with a version of ubuntu-image lacking support for deb822 sources. This has been corrected, and you should now see the correct behavior in the 20240421.1 daily image.
Correction: the ubuntu-image used for the dailies was the right one (as we build from candidate in noble), but we did not have the deb822 images enabled in the definitions for the pi images indeed. This should now be fixed and today’s desktop daily should, in theory, have the right sources list. Can you test it once it’s made available?
For some reason, software-properties-gtk handles these new sources just fine but not the qt interface:

So after some time with a messy Software sources (duplicate: checked items in 1st tab and additional sources in 2nd).
I had to separate each repo like this for ubuntu.sources and delete old sources.list:

It does not work if I put all the repos in the same source (noble noble-updates etc.) as permitted by new format.
On my install from last ISO in ubuntu.sources are no comments but there are in ubuntu.sources.curtin.orig
