[Pkg-owncloud-maintainers] Bug#815963: Warn users about unsupported upgrade path

[Chris]

Package: owncloud
Version: 8.2.2~dfsg-1
Severity: wishlist

Hi,

as ownCloud 7.0.12~dfsg-2 is the latest version of ownCloud in unstable
and experimental is now at 8.2.2~dfsg-1 please warn your users that a
direct upgrade from 7.0.12 to 8.2.2 is not possible.

ownCloud will deny an upgrade because two major versions are skipped. It
needs the following upgrade path to get a working upgrade:

7.0.12 -> 8.0.10 -> 8.1.5 -> 8.2.2
