Comment 1 Randy Barlow 2018-04-12 15:08:50 UTC
As a workaround, I can disable the modular repo:

# dnf upgrade --disablerepo rawhide-modular

Comment 2 Martin Hatina 2018-04-12 15:47:48 UTC
This is probably problem of metadata. I suspect that on rawhide module metadata are in v2, which is not supported by dnf-2.7.5-8. Try updating dnf to dnf-2.7.5-9 or newer.

Comment 3 Petr Ĺ abata 2018-04-12 15:50:44 UTC
Yes, this is because the latest DNF in F28 doesn't support v2.

I created an update for dnf-2.7.5-9 yesterday so that people don't have to download it from koji but this is probably going to bite many.

Comment 4 Merlin Mathesius 2018-04-12 16:30:02 UTC
I have encountered the same issue starting with the docker image "docker.io/fedora:28". "dnf update" followed by "dnf install fedora-repos-modular" works fine. "dnf install fedora-repos-modular" followed by "dnf update" explodes with the exception shown in the description above.

Comment 5 Adam Williamson 2018-04-12 21:50:32 UTC
could the update also include an updated fedora-repos-modular which requires the updated dnf, to avoid fresh installs possibly falling into the same trap as Merlin hit? Does that make sense?

Comment 6 Adam Williamson 2018-04-12 23:37:12 UTC
This actually seems to affect simply booting an install of current Fedora Server 28 and running 'dnf' - it broke multiple openQA tests today:

https://openqa.fedoraproject.org/tests/221593
https://openqa.fedoraproject.org/tests/221589
https://openqa.fedoraproject.org/tests/221584
https://openqa.fedoraproject.org/tests/221587

so obviously +1 blocker.

Comment 7 Fedora Update System 2018-04-12 23:38:14 UTC
dnf-2.7.5-9.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-6aacf0bd62

Comment 8 Patrick Uiterwijk 2018-04-15 01:31:54 UTC
+1 blocker per comment 6.

Comment 9 Fedora Update System 2018-04-15 02:40:25 UTC
dnf-2.7.5-9.fc28 has been pushed to the Fedora 28 stable repository. If problems still persist, please make note of it in this bug report.
