Generally, when apt wants to uninstall in that situation, it means it can't
find the dependency in your sources.  In this case, your .deb specifically
wants libssl0.9.7e, which isn't in Ubuntu, so you'd need to find it
(hopefully at the same place you got the .deb you already installed).  Note
also that it's not libssl version 0.9.x, it's two completely different
packages libssl0.9.7e and libssl0.9.8, so they're intended to both be able
to exist on the same machine.
