I have meet this bug on two cubietrucks from five. My solution was simple: Login to system. Change date to actual. Change root password again (it was changed with invalid datetime.) Reboot. ln -sf /usr/share/zoneinfo/Europe/Moscow /etc/localtime date 071901102015 passwd reboot If you forgot to change root password, you can insert your sd card into linux computer and reset it. mount /dev/sdc1 /mnt sed -e '/root/s/root:[^:]*:[^:]*:/root::1:/' -i /etc/shadow umount /mnt
