Bug#772871: cups: Trigger cycle causes dpkg to fail processing

[Guillem Jover <guillem@debian.org>]

Package: cups
Version: 1.7.5-9
Severity: serious

Hi!

This package can get involved in a trigger cycle. The problem is that
it installs interests on /usr/share/cups/ppd-updaters with files there
provided by cups-filters, which is directly or transitively depended on
by cups itself.


A solution to the above is to simply switch the triggers to their
noawait variants, in this case from «interest» to «interest-noawait»,
as long as they are not critical for the activating packages, which I
cannot tell here. Otherwise a fix might unfortunatly be more involved.

Thanks,
Guillem
