I think this might be caused by Python 3.10.  Older versions produce a warning that 3.10 will break "collections.MutableMapping":

$ python

<stdin>:1: DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.10 it will stop working

I see this behavior in f35 as released. The same problem seems to cause subscription-manager to crash on invocation:

This was already fixed upstream with:
https://github.com/candlepin/subscription-manager/pull/2753

There was no upstream release since then though.

I can see there's already F35 build:
https://koji.fedoraproject.org/koji/buildinfo?buildID=1858632

Can a new Bodhi update be created?

Tested by:

$ sudo dnf update --disableplugin product-id \
                  --disableplugin=subscription-manager \
                  --disableplugin=upload-profile \

(note you have to --disableplugin=... to make dnf work again for normal operations)

This blocks Fedora Copr migration to the Fedora 35 machines, where we plan to build
EPEL 8 packages against RHEL 8 using subscribed Fedora.  Subscription-manager will be
needed on Fedora since CentOS 8 goes EOL soon, and many people will likely try to build
against RHEL using Mock: https://pagure.io/epel/issue/133

Ping, the built version 1.29.21-1 fixes the issue, we just need the Bodhi update.
Installing the current subscription-manager (1.29.18) into F35 totally breaks DNF stack,
so sending the update can not cause any more harm than that.

Please see this update for when the fix for this will come to f35: https://bodhi.fedoraproject.org/updates/FEDORA-2022-1da95f09ca

The update was pushed to stable for f35 some days ago, hence closing.
