Upgrading from PVE 5 to 6 works only with the Gluster packages from the
Debian repository. At least Gluster versions 5.8 to 6.4-1 have conflicts
with our packages.
Signed-off-by: Dominic Jäger <d.jae...@proxmox.com>

Tested on one VM with PVE 5.4 and upstream Gluster (6.4-1) and one
with PVE 5.4 and the Debian Gluster packages (3.8). The upgrade gives
the expected conflicts. The error message remains useful after the
(erroneous) upgrade.
