Can't upgrade Navio2

I am trying to upgrade the Navio 2 distribution using the sudo apt-get upgrade && sudo apt-get dist-upgrade command. However, it does not appear to be able to find the relevant files on the emlid server and I get the error message: Err jessie/main rcio-dkms all 0.6.3
404 Not Found
E: Failed to fetch 404 Not Found

Any suggestions would be appreciated.
