I started seeing messages like this in logs after I applied the 4.3 to 4.4 update:
192.168.0.20 sshd[25622]: Postponed publickey for barney from ::ffff:192.168.0.12 port 40291 ssh2
Some googling revealed that the version of sshd I am now running is chrooted, but the chroot environment is incomplete. Instructions for completing the chroot environment can be found here:
