I've seen this error on recent SSH versions, including the OpenSSH used by OS X and others:
Unable to negotiate with 192.168.77.1 port 22: no matching cipher found. Their offer: aes128-cbc,3des-cbc,aes192-cbc,aes256-cbc
Several people suggest modifying your local ssh client config. However, I'd rather not use 3DES unless I have to. So, I created an alias and put it in .bash_profile:
alias ssho='ssh -c 3des-cbc'
after a quick . ~/.bash_profile
I can ssh with the alias:
Of course, the best fix would be to update IOS on the Cisco gear.

There is a bug with OpenStack Pike deployments using Ansible. When you attempt to create an image in Horizon, you will see the following error:
Followed by this entry in the images list after closing this:
You should still be able to create images via command line, but Horizon won't work.
There is a bug filed for this:
Their fix is simple: connect to the horizon container from an infrastructure node:
lxc-attach -n `lxc-ls -1 | grep horizon | tail -1`
HORIZON_IMAGES_UPLOAD_MODE = 'direct'
HORIZON_IMAGES_UPLOAD_MODE = 'remote'
After that, restart the horizon container
lxc-stop -n `lxc-ls -1 | grep horizon | tail -1`
lxc-start -n `lxc-ls -1 | grep horizon | tail -1`
And simply wait a few minutes. Image creation should work.
