"File too short"??

I keep trying to do dnf update on F22, in order to be able to upgrade it to F23. But when it starts downloading files, it denies them: [....] (243/244): nss-3.21.0-1.1.fc22.i 433 kB/s | 871 kB 00:02 (244/244): pluma-data-1.12.0-1.f 487 kB/s | 2.7 MB 00:05 ----------------------------------------------------------------- Total 2.9 MB/s | 822 MB 04:40 Delta RPMs reduced 750.4 MB of updates to 821.5 MB (-9.1% saved) Running transaction check error: Failed to dlopen /usr/lib64/rpm-plugins/selinux.so /lib64/ librpm.so.7: file too short error: Failed to dlopen /usr/lib64/rpm-plugins/systemd_inhibit.so /lib64/ librpm.so.7: file too short [....] (243/244): nss-3.21.0-1.1.fc22.i 433 kB/s | 871 kB 00:02 (244/244): pluma-data-1.12.0-1.f 487 kB/s | 2.7 MB 00:05 ----------------------------------------------------------------- Total 2.9 MB/s | 822 MB 04:40 Delta RPMs reduced 750.4 MB of updates to 821.5 MB (-9.1% saved) Running transaction check error: Failed to dlopen /usr/lib64/rpm-plugins/selinux.so /lib64/ librpm.so.7: file too short error: Failed to dlopen /usr/lib64/rpm-plugins/systemd_inhibit.so /lib64/ librpm.so.7: file too short The downloaded packages were saved in cache till the next successful transaction.
