[Owncloud] Ubuntu 12.10 fails to update to latest version

[Chris Green]

My Owncloud installation on Ubuntu 12.10 is trying to update itself and
failing with the following message:-

    Failed to fetch
        http://download.opensuse.org/repositories/isv:ownCloud:devel/xUbuntu_12.10/./amd64/owncloud-client_1.4.1-0_amd64.deb
    Size mismatch

So, have I done something wrong or is there something wrong in the
repository?
