I have strange problem in f23 beta

Every action returns only this line:

Last metadata expiration check performed 0:00:00 ago on Wed Sep 30 10:21:21 2015.

ex.:

$ sudo dnf list --refresh

Last metadata expiration check performed 0:00:00 ago on Wed Sep 30 10:22:26 2015.

with --verbose

sudo dnf list --refresh --verbose

I have tried 

dnf clean all

but no difference

Is it normal? Is it bug on my site or I need send it to bugzilla?
