Bug Description
2 bugs are similar but not the same at https:/
host A ubuntu 14.04.3 -- running ssh-server
client B and C
client B 14.04.3 can connect no problem with ssh keys only to host A (to me this means openssh-server is fine on Host A)
Client C 15.10 cannot ssh to host A, openssh cannot or refuses to load identity files; output of ssh -vvv below
$ ssh ubuntu@172.27.20.1 -vv

###at this point connection hangs -- sometimes i get back "ssh_exchange_
permissions on files look OK to me:
$ ls -all .ssh
