Right now all jessie systems have GTK installed (plus all the related underlying Gnome libraries, Harfbuzz, Cairo, Pango, Graphite etc).
The only reason is that gnupg-agent (which gets pulled in by mutt) depends on pinentry-gtk2 | pinentry-curses. Since the first dependency alternative gets tried first, pinentry-gtk is preferred over pinentry-curses.
Installing pinentry-curses in scripts/late-command would probably fix this.
I think we shouldn't have mutt either, as bsd-mailx is already installed anyways and both come from exim4-base via
neodymium:~$ aptitude why mutt i exim4-base Suggests mail-reader i mutt Provides mail-reader neodymium:~$ aptitude why bsd-mailx i exim4-base Recommends mailx i bsd-mailx Provides mailx neodymium:~$
I'm not sure even sure why mutt is installed, "mail-reader" is only a Suggests: of exim4-base after all?
indeed, it looks like it gets dragged in on the first install (even before puppet)
neodymium:~$ zgrep -e mutt -e mailx -e exim /var/log/dpkg.log.3.gz | grep 'install ' 2015-11-10 18:34:40 install exim4-config:all <none> 4.84-8 2015-11-10 18:34:40 install exim4-base:amd64 <none> 4.84-8 2015-11-10 18:34:40 install exim4-daemon-light:amd64 <none> 4.84-8 2015-11-10 18:34:41 install bsd-mailx:amd64 <none> 8.1.2-0.20141216cvs-2 2015-11-10 18:34:43 install exim4:all <none> 4.84-8 2015-11-10 18:34:47 install mutt:amd64 <none> 1.5.23-3
This still happens and we have GTK/Gnome base libs installed on > 1000 servers now, we should really sort this out for stretch...
Ugh! In d-i-test:
faidon@d-i-test:~$ dpkg -l |egrep 'gnupg|mutt|pinentry' ii gnupg 2.1.18-6 amd64 GNU privacy guard - a free PGP replacement ii gnupg-agent 2.1.18-6 amd64 GNU privacy guard - cryptographic agent ii pinentry-curses 1.0.0-2 amd64 curses-based PIN or pass-phrase entry dialog for GnuPG
So that's promising. I'd really prefer to fix it for the existing jessie fleet too though…
Ack for jessie, I'll have a look at the rdepends of the various packages, we should be able to trim these via puppet
This only affected jessie, which is going away and won't specifically get fixed there.
