for support/issues with the Synology packages you should contact the Synology support. The packages you're mentioning here are not provided by owncloud.org or anyone related to it.

they also shouldn't offer you an upgrade from oC 6 to oC8.x as this is an unsupported upgrade path from ownCloud side.

Depending on the oC 8 version they need to provide you the following upgrade path via packages (example 8.2 as target version):

oC 6.0.x -> latest 6.0.x -> latest 7.0.x -> latest 8.0.x -> latest 8.1.x -> latest 8.2.x

If that is not possible the package should be uninstall itself correctly which is only fixable by Synology or the package provider.
