> What is the exact way of upgrading?

Hi Miro,
from a Fedora 23 system (default install):

1) dnf -y update
2) dnf -y install fedora-repos-rawhide
3) enable the rawhide repos
4) dnf -y update

With the same steps we also see bug #1339731

I believe we forgot to add some Conflicts:

Comment 4 Charalampos Stratakis 2016-05-30 06:11:08 EDT
Tested it on Friday and I was able to reproduce the problem, however today when I retested on a clean f23 machine and upgraded to rawhide, it worked as expected with no conflicts.

Dnf got updated so maybe somehow it got resolved? Couldn't find something specific in the release notes however.

Could you retest it and tell me if you are still getting this error?
Comment 5 Charalampos Stratakis 2016-05-30 11:04:52 EDT
Ok I isolated some test cases.

A fedora 23 image was used for all systems, updated with dnf as of May 30.

1) # dnf install fedora-repos-rawhide
# dnf update --enablerepo-rawhide --refresh

Updates complete successfully, machine doesn't reboot however due to probably unrelated issue (rawhide kernel?)

Also the same with:
# dnf update --releasever=rawhide --nogpgcheck --refresh # nogpgcheck for unsigned kernel

2) # dnf distro-sync --releasever=24 --refresh

Everything works

3) # dnf install dnf-plugin-system-upgrade
# dnf system-upgrade download --refresh --releasever=24

As documented here [0] and it works also.

4) # dnf update --releasever=24 --refresh
This is where the error appears and also the bug #1339731

Comment 6 Miro Hrončok 2016-05-30 13:54:53 EDT
The explicit conflict should solve even potential problems and cannot do any harm (expect when done wrong).
Comment 7 Alexander Todorov 2016-05-31 05:05:52 EDT
I've tested today with the steps from comment #2.  Did not see any conflicts, the resulting system has:
