Bug#195604: tetex-bin: broken guard for tetex-bin/cnf_name

["Aaron M. Ucko" <ucko@debian.org>]

Package: tetex-bin
Version: 2.0.2-4
Severity: grave
Tags: sid
Justification: renders package unusable

> Preparing to replace tetex-bin 2.0.2-3 (using .../tetex-bin_2.0.2-4_i386.deb) ...
> dpkg: error processing /var/cache/apt/archives/tetex-bin_2.0.2-4_i386.deb (--unpack):
>  subprocess pre-installation script returned error exit status 1

The problem seems to be with

    flag=`ls /etc/texmf/texmf.d/*[^\.cnf$] 2> /dev/null | egrep -v '(.dpkg-.*|~)$'`
    if [ X"${flag}" != X ]; then
	db_input high tetex-bin/cnf_name || true
	db_go || true
    fi

in particular, if egrep doesn't find anything, then the assignment to
flag returns false (!).  Your shell globbing is also a bit off; I'd
suggest something like

    if ls /etc/texmf/texmf.d 2>/dev/null | egrep -vq '(\.cnf|\.dpkg-.*|~)$'; then
	db_input high tetex-bin/cnf_name || true
	db_go || true
    fi

Please test whatever code you end up using before releasing it, both
with and without non-.cnf files!
