Hi,

during a test with piuparts I noticed your package removes files that
were installed by another package.
The removed files were already present before the package was installed,
they may have been shipped or created by a dependency.

This could be a violation of policy 10.7.4 ("Sharing configuration
files"), see
http://www.debian.org/doc/debian-policy/ch-files.html#s10.7.4
or policy chapter 6 ("Package maintainer scripts..."), see
http://www.debian.org/doc/debian-policy/ch-maintainerscripts.html
or policy 7.6 ("Overwriting files..."), see
http://www.debian.org/doc/debian-policy/ch-relationships.html#s-replaces

If a directory is used by several packages, all should ship it as part
of the package (possibly empty, using $package.dirs to create it), and
no package should mkdir/rmdir it in the maintainer scripts as dpkg will
take care of this.

>From the attached log (scroll to the bottom...):

0m39.3s ERROR: FAIL: After purging files have disappeared:
  /etc/ssl/certs/        owned by: ca-certificates, openssl


The postrm contains code to remove that directory:

        # Clean up even if openssl is removed before ca-certificates.
        # (Which is what piuparts does.)
        [ -d /etc/ssl/certs ] && rmdir --ignore-fail-on-non-empty /etc/ssl/certs
        [ -d /etc/ssl ] && rmdir --ignore-fail-on-non-empty /etc/ssl

which should not be neccessary if both packages ship /etc/ssl/certs.
And if the directory is left behind after purge, its a dpkg bug,
probably #316521.


cheers,

Andreas
