As a friendly tip for anyone else who:
- Just upgraded to Ubuntu 14.10
- Use Mysql Workbench a lot
- Use the built in TCP/IP over SSH to connect to remote servers.
There’s a big chance that you saw this:
In Ubuntu 14.10 the package python-paramiko was upgraded to 1.15. The package is used by Python apps to create ssh connection. In version 1.15 it seems that paramiko has problem with some servers due to a mismatch in what protocols to support. End result is that your MySQL Workbench cant connect using an ssh connection
Downgrade to python-paramiko 1.10 that was shipped with Ubuntu 14.04.
Run these two commands in the terminal.
$ wget http://launchpadlibrarian.net/167351511/python-paramiko_1.10.1-1git1build1_all.deb
$ sudo dpkg -i python-paramiko_1.10.1-1git1build1_all.deb
