Bug#765668: cups: dpkg: cycle found while processing triggers:

[Thorsten Glaser <tg@mirbsd.de>]

Package: cups
Version: 1.7.5-4
Severity: serious
Justification: fails to install

Hi,

I’ve been having dpkg messages about cycles in triggers for a while
recently, but they all involved multiple packages (mostly cups,
postgresql, man-db) and were resolved just configuring the packages
again.

Today is different:

1|root@tglase:~ # dpkg -a --configure                                          
Setting up libc-bin (2.19-11) ...
dpkg: cycle found while processing triggers:
 chain of packages whose triggers are or may be responsible:
  cups -> cups
 packages' pending triggers which are or may be unresolvable:
  cups: /usr/share/cups/ppd-updaters
dpkg: error processing package cups (--configure):
 triggers looping, abandoned
Errors were encountered while processing:
 cups

This repeated for several times, only the fourth repeated
call to “dpkg -a --configure” gave:

1|root@tglase:~ # dpkg -a --configure                                          
Setting up cups (1.7.5-4) ...
Updating PPD files for cups ...
Updating PPD files for openprinting-ppds ...

So I guess there may be something wrong with the cups package.

Feel free to reassign to some other package if the bug is not
with cups, or something.
