Running transaction check
Error: transaction check vs depsolve:
libmicrohttpd.so.12()(64bit) is needed by kodi-15.2-2.fc24.x86_64
To diagnose the problem, try running: 'rpm -Va --nofiles --nodigest'.
You probably have corrupted RPMDB, running 'rpm --rebuilddb' might fix the issue.
09:28 root@puchatek:rebuild# 

"To diagnose the problem, try running" and "You probably have corrupted RPMDB"? There should be better error messages cause now it sounds to me like "I have no idea what is wrong so will look into crystal ball".

Version-Release number of selected component (if applicable):

09:28 root@puchatek:rebuild# dnf --version
  Zainstalowane: dnf-0:1.1.3-1.fc24.noarch o 2015-10-19 11:21
  Zbudowane    : Fedora Project o 2015-10-14 16:46

  Zainstalowane: rpm-0:4.13.0-0.rc1.11.fc24.x86_64 o 2015-11-09 10:56
  Zbudowane    : Fedora Project o 2015-11-06 15:37

How reproducible:


Actual results:

No idea what is wrong and why. Should I ignore it or run suggested commands even if have no idea what they do and is it safe?

Expected results:

Some clear message.

Additional info:

Added "--refresh" to dnf call and all went fine.

This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.

More information and reason for this action is here:
Comment 2 Fedora Admin XMLRPC Client 2016-07-08 05:32:00 EDT
This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.
Comment 3 Jaroslav Mracek 2017-05-19 13:37:30 EDT
I just want to provide additional information. The error message appears, when library libsolv provide set packages for transaction but during rpm check some error appears. We really don't know the issue, but we try to provide something. We provide error plus some suggestion. I believe that there were situations that were possible to solve by suggestions.

From report above I can see the problem:
libmicrohttpd.so.12()(64bit) is needed by kodi-15.2-2.fc24.x86_64

That means that solver has different data set then rpm. Probably in this case different information about installed packages. I don't know if such a problem can be caused by corrupter rpm db. 

For now we don't have anything better, therefore I am closing it.
