- Progress report
  - Some changes have happened in our contributor team. Yuvraj Aseri has failed on mid-term and 
    Gayatri Kapse's project of updating libcupsfilters, CPDB, etc. to IPP Everywhere 2.0 turned 
    out to be unnecessary and so Till moved her over to do the native Gutenprint Printer 
    Application. With that we have now 5 GSoC contributors plus 1 volunteer.

(0) CUPS Snap NOT in Ubuntu 23.10 (Till)
https://discourse.ubuntu.com/t/cups-snap-call-for-testing/
https://ubuntu.social/@till/110945873056733624 (Mastodon)
https://www.omgubuntu.co.uk/2023/08/ubuntu-23-10-wont-use-cups-snap

- Progress report
- Sorry for the false alarm last month. Unfortunately, we had to step back from the switchover.
So Ubuntu 23.10 will, as 23.04 and before, come with a printing stack in Debian packages.

- As Till told last month, he had conducted the switchover together with Sebastien Bacher, and
so Ubuntu 23.10 (Mantic) was using the CUPS Snap as printing stack and so was forced into the
New Architecture. Principally this works, but only on the command line, or on headless
servers.

- What was missing is the desktop integration. Till tried to rush in the changes in the
"Printers" module of GNOME Control Center getting it just working without any UI design
fanciness and put Mohit Verma under some pressure, but this turned out not being that easy.

- Also Ubuntu is not only the original distribution from Canonical, with GNOME desktop. There
are many so-called flavors, distributions derived from the original Ubuntu and also having
the same release cycles as the original Ubuntu. In most cases they have a different desktop,
but also versions for special tasks, like education, or media streaming an editing are under
them. Many of them do not use the current GNOME Control Center, but other printer setup tools.

- This caused a lot of discussion in a Ubuntu Discourse thread, especially the leaders of
several Ubuntu flavors chimed in. Till tried to calm people down and bring in ideas for quick
solutions, like providing a modified GNOME Control Center with all modules but the "Printers"
module removed, for example, which could be installed as independent printer setup tool on
any distro.

- But this does not cover everything and already being after Feature Freeze it would be
impossible for all these flavors getting ready for the New Architecture, and therefore we
have pulled back.

- And as Till always keeps the community up to date, between the OpenPrinting News posts via
Mastodon, it made it right away into OMG! Ubuntu and following that we got also a video by
Brodie.

- So for now Till will concentrate on printing and scanning integration in the all-Snap distro
Ubuntu Core Deskop, using the CUPS Snap, the Printer Application Snaps, Akarshan Kapoor's
scanning support in PAPPL for Scanner Application Snaps, Mohit Verma's work on the GNOME
Control Center, and Gaurav Guleria's and Kushagra Sharma's work on CPDB and print dialogs.
If all this is working, we will reconsider the switchover of the "classic" Ubuntu, to avoid
breaking an LTS (24.04) in Ubuntu 24.10 at the earliest.
