And so it is. That isn't the problem.

That means what is say: No package ia32-libs with version >= 20090808 is
going to be installed.
The big question now is WHY?
Usualy this error means that ia32-libs depends on something that is
uninstallable. To find out the simplest way is to run
sudo apt-get install ia32-libs-libssh2 ia32-libs
You might get the same kind of error again and then just keep adding the
respective packages to the command line till it will give you a "can not
be installed" error (or other). Then you've found the culprit.
On a side note: libssh2-1 is already included in ia32-libs and you will
get a file override conflict trying to install ia32-libs-libssh2 with
current ia32-libs. Whatever needs this package needs to be rebuild
against a newer ia32-libs.
