Como corrigir o erro dpkg: error processing colord (--configure):

Question

Eu atualizei meu Ubuntu de 11,10 para 12,04. Finalmente eu posso achar que quando eu tento instalar alguns pacotes, ele mostra um erro.  depois de ler algum blog eu tentei corrigir esse erro "sudo dpkg --configure -a". mas quando eu executo este comando ele mostra outro erro isso

Answer 1

Tente isto:

[ -f /etc/gshadow.lock ] && sudo rm /etc/gshadow.lock
[ -f /etc/shadow.lock ] && sudo rm /etc/shadow.lock
[ -f /etc/passwd.lock ] && sudo rm /etc/passwd.lock
[ -f /etc/group.lock ] && sudo rm /etc/group.lock
sudo dpkg --configure -a

Isso corrige isso para mim:

sudo delgroup scanner  
sudo apt-get install colord

Isso fez isso por mim. Abaixo, os passos diagnósticos que fiz.

se você olhar para /var/lib/dpkg/info/colord.postinst - e adicionar set -x no topo e executá-lo manualmente ( /var/lib/dpkg/info/colord.postinst configure ) - não será possível adicionar o scanner, e se você se livrar de --quiet , diz:

sudo addgroup --system scanner  
addgroup: The group 'scanner' already exists and is not a system group. Exiting.
