Hi Sam, thanks for your message. After fsck and reboot, I did:

# rpm --rebuilddb

which finished without errors. Then I verified the versions of dnf:

# rpm -q dnf
dnf-1.1.1-2.fc22.noarch
dnf-1.1.3-1.fc22.noarch

and verified the newer version of the package:

# rpm -V dnf-1.1.3-1.fc22.noarch

so I removed the older version:

# rpm -e --nodeps dnf-1.1.1-2.fc22.noarch

The problem is with systemd, which is NOT duplicated:

# rpm -q systemd
systemd-219-24.fc22.x86_64

# rpm -V systemd
S.5....T.  c /etc/sysctl.conf
.M.......    /var/log/journal

Then again:

# rpm --rebuilddb

and I tried to remove duplicated packages:

# dnf remove $(dnf repoquery --duplicated --latest-limit -1 -q)
Dependencies resolved.
Error: The operation would result in removing the following protected 
packages: systemd, dnf.

but it insists in removing systemd and dnf again.

How can I proceed next?

Many thanks,
German.
