Desinstalar o Plex Media Server quebrado a partir de 15.04

Question

Eu tentei instalar o Plex Media Server no Ubuntu 15.04, mas não funcionou por causa da migração para o systemd do Upstart. Infelizmente, parece que não consigo desinstalá-lo agora, já que os retornos de chamada erraram e impediram que o dpkg desinstalasse o pacote. Existe uma maneira de desinstalar forçadamente o pacote?

Veja o que acontece quando tento desinstalar:

Esta linha na saída:

% bl0ck_qu0te%

sugere que systemctl esteja chamando update-rc.d e a única linha plausível que faz isso é:

% bl0ck_qu0te%

Comentando ou cancelando o erro, deve ser feito.
