If this doesn't work, try to identify the actual package
that caused the problem.  That way you file a bug against
it- which is a major step toward getting it fixed.

1. apt-get -s install ssh

...that tells you which packages would get installed if you
installed.  Next try to install each package separately and
check your network connection after each one.

2. apt-get -s install (pkg)=(version)

...check to see if a particlar package can install simply
(with no dependencies).  find one that is a simple
(one-package) install.

3. apt-get install (pkg)=(version)

... install one of the packages that ssh depends on

4. check to see if your problem has recurred.  if not,
continue with the next dependent package.  if so- that last
package was your culprit

Also check with 'route' to see that your default connection
is what you expect it to be.  If you ifdown connections you
aren't using if should be OK.
