Bug#852470: uctodata,libucto2: leftover conffiles after upgrades

[Andreas Beckmann]

Package: uctodata,libucto2
Severity: important
Control: found -1 0.4-1
Control: found -1 0.9.6-1

jessie-> sid upgrades:

ucto.maintscript is missing, doing rm_conffile on the conffiles shipped
in jessie (use 0.9.6-2~ as prior version, if this gets fixed in -2).
If there was a post-jessie version shipping more conffiles in /etc,
clean them up as well.

  ucto: obsolete-conffile /etc/ucto/exotic-eos.eos
  ucto: obsolete-conffile /etc/ucto/nl_afk.abr
  ucto: obsolete-conffile /etc/ucto/tokconfig-nl

frog looks fine

stretch -> sid upgrades:

  libucto2:amd64: obsolete-conffile /etc/ucto/textcat.cfg

  uctodata: obsolete-conffile /etc/ucto/spa.abr
  uctodata: obsolete-conffile /etc/ucto/por.abr
  uctodata: obsolete-conffile /etc/ucto/nld_afk.abr

frog looks fine, too


That's not RC, the upgrades went smooth, but it would still be great to
get this cleaned up properly.

But lets take a detailed look what happened here:

You probably shouldn't call rm_conffile on the symlinks owned by
uctodata - these are no conffiles, but you seem to confuse dpkg by doing
this. Removing the conffiles from jessie is better left to
ucto.maintscript.

I think you found a bug in dpkg here :-)

libucto2.maintscript is missing this line:

rm_conffile /etc/ucto/tokconfig-generic 0.9.6-2~


Let's prepare these fixed in git s.t. I can test the upgrade paths
(especially testing the stretch->sid path must happen before the sid
version migrates), but let's postpone the upload until after the current
packages migrated to testing.
