Remaining .dhelp files prevent directory removing on purge
I have a package (gri-html-doc) which used to provide documentation in
/usr/share/doc/gri-html-doc/html/ and I have sinced moved the docs to
Upon upgrading from one version to the other, I get the warning:
dpkg: warning - unable to delete old file `/usr/share/doc/gri-html-doc/html':
Directory not empty
That directory contains the old .dhelp file, which I didn't create; I
use a doc-base file.
Was I suppose to delete /usr/share/doc/gri-html-doc/html/.dhelp
in my old package's prerm?
Since it's too late to do that, do I delete it and the html directory
(if empty) in the new package's preinst? Or even in the postinst?
