It appears that Saucy has seen it's end of life according to the Ubuntu schedule on July 17 2014. dCore plans to support Debian and Ubuntu releases as long as they are in their active lifecycle. ub-dCore-saucy therefore will be retired and users are advised to upgrade to either Trusty or Utopic. Trusty is the long term release that will be supported by Ubuntu until April 2019. Utopic will be supported until July 2015.
Existing Saucy installs should continue to work, but will not receive dCore updates.
