Renaming of conf file fails

[Gunnar Hjalmarsson]

[Impact]
The fix of <https://bugs.debian.org/853848> wasn't accomplished properly. Renamings of conf files weren't addressed in maintainer scripts, upgrades from previous versions fail in this respect, and the package system generates warning messages.

The problem has been reported in Debian, and the purpose of this bug report is to keep track of the progress.

[Justification]
This config file is broken in xenial and will still be broken on upgrade to bionic, which means the fonts in question will not be available to the system as intended if the user has upgraded.

[Test case]
For each of
- fonts-beng-extra
- fonts-deva-extra
- fonts-gujr-extra
- fonts-guru-extra
- fonts-orya-extra
- fonts-telu-extra:

* Purge the package if installed and clean up possible leftovers
  due to the issue.

* Install the Xenial version of the package and find that the symlink
  in /etc/fonts/conf.d incorrectly points to a directory.

* Install the version in bionic-release and find that the attempt
  to fix the issue fails

* Install the version in bionic-proposed and find that it fixes the
  issue and that the symlink now correctly points to the conf file.

[Regression potential]
Because this modifies maintainer scripts there is possibility of introducing a regression that will cause the package to fail to unpack.

Fixed in 2.0-4ubuntu1 for cosmic.

Of these packages, fonts-guru-extra is the only one that in practice I see is affected by this bug on a continuously-upgraded system (16.04 -> 16.10 -> 17.04 -> 17.10 -> 18.04), so is the only package I am currently intending to SRU.

[Gunnar Hjalmarsson (gunnarhj)]

@Steve: fonts-guru-extra affects everyone, since fonts-guru is in desktop-common in Xenial, and thus is indeed the most important package to fix.

OTOH, the issue is present for all the above packages for those affected. Will try to fix them using the same method as you did for fonts-guru-extra.

It really isn't. I have all of these packages installed and
fonts-guru-extra is the only one that was affected in practice.

[Gunnar Hjalmarsson (gunnarhj)]

But when did you install the other packages? I suspect that you did so when upgrading to 17.10, where fonts-indic was added to ubuntu-desktop. In that case you never had the Xenial version of those packages which may explain why you didn't stumble upon the upgrade issue for those.

Please see the attachment, which shows the issue for fonts-beng-extra.

fonts-telu-extra is mentioned at https://bugs.debian.org/854163, but it does not seem to suffer from the same issue as the other ones. Dropping the fonts-telu-extra tasks.
