Como posso remover à força um pacote do Ubuntu manualmente?

Question

Eu postei isso no ServerFault e recebi algumas perguntas úteis, mas nenhuma resposta em termos do que posso fazer. O que, em um nível baixo, posso fazer para exorcizar completamente um pacote que está sobrecarregando as atualizações do aptitude?

Eu tenho um pacote libssl-dev instalado, possivelmente porque não tenho certeza se ignorei o gerenciador de pacotes e ele é visível no gerenciador de pacotes, mas não desaparece.

root@li393-189:/home/jonathan/python-amazon-product-api-0.2.5# aptitude purge l
ibssl-dev

Eu quero que o libssl-dev instalado atualmente seja substituído por uma nova instalação de pacote. Nenhuma configuração de aptidão que eu já tenha visto irá removê-lo.

Como posso remover o pacote existente para poder reinstalá-lo do zero?

- EDITAR

@Brigo, eu tentei com o aptitude em vez de apenas o apt-get, mas o apt-get dá o que me parece um equivalente aparente:

root@li393-189:/home/jonathan/python-amazon-product-api-0.2.5# apt-get remove lI want the presently installed libssl-dev to be replaced with a fresh package installation. No configuration of aptitude I've seen yet will remove it.

How can I remove the existing package to be able to reinstall it from scratch?

--EDIT--

@Brigo, I had tried with aptitude rather than just apt-get, but apt-get gives what looks to me like an apparent equivalent:

root@li393-189:/home/jonathan/python-amazon-product-api-0.2.5# apt-get remove l
