Bug#911620: shared-mime-info, gconf2: trigger cycle during upgrade from stretch to buster

[Andreas Beckmann]

Package: shared-mime-info,gconf2
Severity: serious
User: debian-qa at lists.debian.org
Usertags: piuparts
Control: found -1 1.10-1
Control: found -1 3.2.6-5
Control: affects -1 + microhope

Hi,

during a test with piuparts I noticed your package fails to upgrade from
'stretch'.
It installed fine in 'stretch', then the upgrade to 'buster' fails.

>From the attached log (scroll to the bottom...):

  Setting up libgl1-mesa-glx:amd64 (18.1.7-1) ...
  dpkg: cycle found while processing triggers:
   chain of packages whose triggers are or may be responsible:
    shared-mime-info -> gconf2
   packages' pending triggers which are or may be unresolvable:
    shared-mime-info: /usr/share/mime/packages
    libc-bin: ldconfig
    gconf2: /usr/share/gconf/schemas
  dpkg: error processing package shared-mime-info (--configure):
   triggers looping, abandoned


This was observed during a 2-stage upgrade from stretch to buster:
  apt-get upgrade && apt-get dist-upgrade
Both shared-mime-info and gconf2 were already upgraded successfully
during the first stage.
The package being tested was microhope.

IIRC shared-mime-info switched to no-await triggers - so this trigger
cycle problem should have vanished...


cheers,

Andreas
