I have read this AU Q&A titled: MySQL Workbench for Ubuntu 12.04 LTS [duplicate] and installed mysql-workbench-gpl-5.2.43-1ubu1204-i386.deb. When setting up a connection to the MySQL running on localhost or remotely, I get this error:
Connecting to MySQL server localhost... Cannot start SSH tunnel manager
I'm not sure what else to install. BTW, with almost no effort MySQL navigator works just fine to the same systems.
My system is:
Linux steamboy 3.2.0-31-generic-pae #50-Ubuntu SMP Fri Sep 7 16:39:45 UTC 2012 i686 i686 i386 GNU/Linux
and I grabbed the 32-bit workbench. I'm running 12.04 with all current updates.
