Well there are two issues here: (a) significant manual intervention required to make printing work after upgrading F35 -> F36 if printer supports ipp-usb (most printers do), but this is expected; (b) my printer super broke. We don't know how many users are affected by (b) or not: so far, I suppose I'm the only person to report this trouble? We should probably not block release on (b) unless the problem is widespread.

(a) might very well be worth blocking on though, because it is extremely unfortunate. But this situation is actually expected. I'm certain we'll receive a huge number of complaints from users if we release like this. Maybe devel@ would be a good place to discuss this, so I'll respond there.

Well, deleting a printer doesn't seem impossibly hard, and in theory that's all that should be required. Maybe it just seems hard to me because my printer isn't working. :D

I'm still trying to understand the details, but it seems this is going to be a major mess for F36. This will probably affect a sky-high number of users.

I believe this touches on these two criteria:
https://fedoraproject.org/wiki/Fedora_36_Final_Release_Criteria#Printing
https://fedoraproject.org/wiki/Fedora_36_Beta_Release_Criteria#Upgrade_requirements

If the affected user base is as large as I expect, I believe this is:
FinalBlocker +1
(even if we had to waive it in the end due to technical challenges). I'll ask Zdenek some questions in the mailing list to figure out more details.

This is my first attempt at some human-readable summary:
https://ask.fedoraproject.org/t/common-issues/20975

I'm very concerned that the new print system might not work with Firefox, investigating:
https://bugzilla.redhat.com/show_bug.cgi?id=2066528#c4
https://bugzilla.redhat.com/show_bug.cgi?id=1983403

Zdenek, the CUPS maintainer, removed the weak dependency on ipp-usb for F36, which means new installations/upgrades shouldn't hit the described issue. Unless it's re-enabled again, I think this blocker proposal can be cancelled once the updates hit stable:
https://bodhi.fedoraproject.org/updates/FEDORA-2022-7f4925bd0a
https://bodhi.fedoraproject.org/updates/FEDORA-2022-5eac55ee86

I agree, that will guarantee we avoid all issues for F36.

FinalBlocker -1

as there is no reason to block on this issue.

Please explain. If you mean "no reason to vote, because it has been reverted", than no, we have to vote, see https://bugzilla.redhat.com/show_bug.cgi?id=2066528#c49

FinalBlocker +1

But I'm sure we all agree that we can drop the blocker designation once these updates reach stable, not when the underlying bug is actually fixed (we still don't know what's wrong and don't expect it to be fixed).

https://bodhi.fedoraproject.org/updates/FEDORA-2022-5eac55ee86

These two updates are now stable, and I verified that Fedora-Workstation-Live-x86_64-36-20220406.n.0.iso doesn't contain ipp-usb, nor ipp-usb gets installed if you update an F36 Beta installation. So I believe we can now remove the blocker tag.

Release F36 is no longer tracked by BlockerBugs, closing this ticket.
