As impressoras do servidor de impressão CUPS pararam de funcionar, quando reinicio o serviço fica aparecendo mensagem de "No such interface", alguém sabe o que pode ter acontecido ?
As impressoras continuam na rede, nada foi alterado.
Tentei limpar os arquivos da fila de impressão do /var/spool/samba e /var/spool/cups mas não funcionou.

No arquivo /var/log/cups/error_log:
