[Debconf-devel] Bug#366108: debconf: Misconfigured package can
block further installs, and can't be reconfigured

I noticed this while doing a dist-upgrade.
The package tex-common asked for a group to own font files,
and I mistyped it. tex-common then failed in its post-install
script, and blocked further upgrading.
Now, this would be easy to fix if I could use
to correct the misspelled group name. But
dpkg-reconfigure won't touch such a package because it is
"broken". This is a problem, because the problem cannot
be fixed. dpkg-reconfigure should simply run and ask the
questions in such a case, so I can do a
apt-get -f install (or similiar) later.
Reconfiguring the not fully installed package proved impossible.
I tired removing it the excessive way, with
dpkg --force-depends --remove tex-common,
but the broken config remained. I was not asked any questions
on package reinstall, so it broke the same way! I had hoped to
get the config questions again, so I could correct the
wrong group name. And keep any other setting, of course.
I had to use dpkg --force-depends --purge tex-common, then
I could reinstall the package. This is bad, as a purge
destroys each and every setting completely. Fortunately,
tex-common only have a couple of settings, but
imagine this scenario happening with the xserver, the ldap server,
or some other really complex software.
The solution seems simple to me - please let dpkg-reconfigure
work on packages that are broken due to a failed post-install.
It will then be possible to fix bad settings, without
clearing all other settings for the same package. And without resorting
to hairy options like --force-depends.
