Answer 1

Você pode tentar atualizar o pacote antes de limpá-lo. Em alguns casos, o novo pacote consertará o script de remoção ( dpkg é feito para que novos pacotes possam consertar até mesmo os scripts de transição de pacotes antigos).

Se isso não funcionar, dê uma olhada em /var/lib/dpkg/info/openqrm.postinst , como Kyle sugeriu, localize a linha que falha, comente e tente purgar novamente. Repita até o sucesso.

    

Answer 2

O seguinte funcionou para mim:

• rm -rf / var / lib / dpkg / info / openqrm. *
• rm -rf / usr / share / openqrm
• rm -rf / etc / default / openqrm
• rm -rf /etc/init.d/openqrm
• apt-get purgar openqrm

Answer 3

Tente tocar no arquivo que está faltando. Se este é apenas um arquivo faltando, pode ser um ótimo solução alternativa.

touch /usr/share/openqrm/etc/openqrm-server.conf

Agora tente remover o pacote com o apt-get ou o aptitude.

    

Answer 4

Veja /var/lib/dpkg/info/openqrm.postinst e veja o que está tentando fazer

    

Answer 5

Existe um poste aqui sobre o mesmo tipo de erro (pacote diferente, no entanto). Você tentou dpkg --force-all ainda?
