Subject: [Debian-in-workers] Bug#866051: fonts-guru-extra: upgrade does not
 clean up obsoleted directories
References: <149852082426.15358.1681139953934858878.reportbug@hysteria.proulx.com>
Message-ID: <11f12e6f-3672-3499-4ccd-8a2d8b53f76e@ubuntu.com>

Want to mention that we have fixed this in Ubuntu for fonts-guru-extra 
as well as fonts-{beng,deva,gujr,orya}-extra. We used preinst scripts; 
please see the attached example.
