Hi Michał I've removed the owncloud package from AUR as it was several versions out of date and not buildable at the current stage. The actual maintainer made a request for the deletion. If you're still interested in maintaining owncloud and your others owncloud packages, you can simply clone it from AUR, upgrade and restore it. I'm temporarily denying the deletion request in the case you're still interested in maintaining it along with owncloud, otherwise it will be deleted for the missing owncloud dependency. Best regards -- Muflone
