Eu tenho uma máquina virtual Debian 6 VMWare que eu uso principalmente via SSH (mas ocasionalmente via GUI).
A cada poucos minutos, a seguinte mensagem é impressa no meu terminal:
CUPS config timestamp change detected but old config retrieved via interface!
Por um tempo, eu ignorei. Então, eu desinstalei o CUPS:
$ sudo apt-get remove cups
$ sudo apt-get autoremove
e reiniciado. Ainda estou recebendo a mensagem.
Como na terra posso pará-lo? Eu nunca, nunca vou querer imprimir a partir desta máquina.
a) Remover as taças não remove o CUPS.
b) você quer usar apt-get purge não remover, provavelmente.
Você quer eliminar esse lote, no mínimo. Você pode fazer isso com um curinga ou regex.
apt-get purge '^cups'
parece excluir todos os pacotes que começam com xícaras, mas na verdade queremos todos os arquivos contendo xícaras. Especialistas em regex para o resgate, por favor. :-) Veja apt-get purge '^cups' output abaixo.
(UPDATE: Abaixo os comentários de Paul, o GNOME aparentemente insiste em ter algumas bibliotecas de CUPs instaladas, então eu sugeri que ele simplesmente removesse as coisas do frontend, então na verdade talvez ele realmente queira apt-get purge '^cups' ).
