--- Comment #15 from Mukundan Ragavan nonamedotc@gmail.com --- Several of these are all already owned.
1/ For example,
$ rpm -q --whatprovides /usr/share/icons/hicolor/16x16/mimetypes hicolor-icon-theme-0.15-4.fc26.noarch keepassx-2.0.3-3.fc26.x86_64
In this case, we are at this section of the packaging guidelines -
https://fedoraproject.org/wiki/Packaging:Guidelines#File_and_Directory_Owner...
Specifically, here-
https://fedoraproject.org/wiki/Packaging:Guidelines#The_directory_is_also_ow...
We do not need hicolor-icon-theme, but hicolor-icon-theme is required by pretty much every graphical environment.
So, it is proper for hicolor to own these directories.
2/ We need shared-mime-info for a graphical package to function
$ rpm -q --whatprovides /usr/share/mime/packages shared-mime-info-1.8-2.fc26.x86_64
So, this is safe to ignore as well.
3/ /usr/share/mimelnk
This is not owned by any other package and so, keepassxc should own it.
$ dnf repoquery --whatprovides /usr/share/mimelnk/ determining the fastest mirror (6 hosts).. done. Fedora 26 - x86_64 - Test Updates

Does this clear up?
