Comment 11 Fedora Blocker Bugs Application 2019-09-24 13:08:04 UTC 
Proposed as a Blocker for 31-final by Fedora user bepvte using the blocker tracking app because:

 I believe that this bug should block the release of fedora 31 final, as it causes graphical upgrades to fail when the user uses common external repositories without any errors in their .repo files. 
I believe this violates the beta release criterion "Installing, removing and updating software".

What do you mean by *graphical*? Comment 0 is about running "dnf system-upgrade", i.e. a command-line command. 

Somebody please provide clear reproduction steps. When exactly does this crash happen? The command line stated here is "dnf system-upgrade upgrade", which is a non-supported keyword according to dnf.plugin.system-upgrade man page.
Comment 14 Jonathan Haas 2019-09-26 11:56:14 UTC 
This bug is probably a duplicate of Bug 1746346 and that bug states that this happens with command line "dnf system-upgrade" as well as graphical packagekit updates.

Comment 16 Kamil Páral 2019-09-26 13:16:06 UTC 
Thanks, the errors look the same and Pavla posted the same PR for both, so I merged them. Do I understand correctly that no harm is done to the system, the traceback happens before any package gets installed/updated? Also, the traceback happens during the "offline update" screen? Pavla or anyone, can you specify what the trigger is? A repo with some specific configuration?

My specific crash happens after I use the "restart and update" button to restart and begin an update. I also checked "dnf history" and didnt see a transaction, as well just now I ran "rpm -Va" and everything looks fine. I dont know if external repos caused the problem or not, but I do know I use external repos and attached an archive of their .repo files to this bug.
Comment 18 Dima Ryazanov 2019-09-27 05:41:36 UTC 
I'm having the same problem. I used "dnf system-upgrade" to upgrade to F31 - and since then, the graphical upgrade has been broken (same as in the comment above - the exception happens after rebooting after clicking "restart and upgrade")
Comment 19 Fedora Update System 2019-09-27 06:39:50 UTC 
FEDORA-2019-6a6b241835 has been submitted as an update to Fedora 31. https://bodhi.fedoraproject.org/updates/FEDORA-2019-6a6b241835
Comment 20 Pavla Kratochvilova 2019-09-27 06:41:29 UTC 
Kamil, yes, the traceback happens before any package is modified.

As for the trigger, for the command-line tool, it happens when you run "dnf system-upgrade reboot" without runing "dnf system-upgrade download" first (or running the download with older version). I am not sure how the system-upgrade plugin is used in PackageKit.

Comment 24 Geoffrey Marr 2019-09-30 22:24:19 UTC 
Discussed during the 2019-09-30 blocker review meeting: [0]

The decision to classify this bug as an "AcceptedBlocker" was made as it violates the following criterion:

"The installed system must be able appropriately to install, remove, and update software with the default tool for the relevant software type in all release-blocking desktops (e.g. default graphical package manager)..."
