Como faço para reinstalar o python no meu servidor Ubuntu 12.04 usando o apt-get?

Question

Como eu estraguei totalmente a instalação do meu python, excluí todos os arquivos python manualmente e agora estou tentando reinstalá-lo.

Quando digito apt-get install --reinstall python2.7 , recebo esta mensagem de erro:

0 to upgrade, 0 to newly install, 1 reinstalled, 0 to remove and 0 not to upgrade.
3 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.

 python-minimal
 python2.7
 python
E: Sub-process /usr/bin/dpkg returned an error code (1)

Como posso me recuperar disso?

Edit: Além da sugestão do kubahaha, eu tentei

# dpkg -P python2.7

e não funcionou por causa de dependências. Isso removeu os pacotes:

# dpkg -P libapache2-mod-wsgi libpython2.7 python2.7

Mas quando eu tentei:

# apt-get install python2.7 libapache2-mod-wsgi libpython2.7

Recebi esta mensagem de erro:

/var/lib/dpkg/info/python-minimal.postinst: 4: /var/lib/dpkg/info/python-minimal.postinst: python2.7: not found

O dpkg / apt parece-me muito frágil, pois, uma vez que o sistema está em mau estado, parece que nunca conseguem voltar a estar em bom estado.

Purgue-o e instale novamente

1. sudo dpkg -P python2.7
2. sudo apt-get install python2.7
