out of topic, F22 Gnome SW admin password rejection

Hi,
I know it's out of topic, but I have had today urgent Gnome problems with F23 Final TC9 Gnome SW and now really unexpected situation with Gnome SW F22.
Installed F22, last build, to a 32GB usb flash medium. dnf su admin pw, ok. dnf update ok. Tried to install apps via the Gnome SW. Admin password requested, correct admin pw always rejected. Any idea? Coincident behaviour with the previous problems of F23 TC9 Gnome SW? Gnome SW F23 TC9 rejected installation of Gimp, Xsane etc.
Kind Regards
