Trying to load responder has brought up a dependency issue. When it is invoked responder wants to load Git, but it is no longer available at the path that is being called by opkg.
root@turtle:/etc/turtle/modules# opkg update > /dev/null && opkg install git
* opkg_download: Failed to download http://downloads.openwrt.org/chaos_calmer/15.05.1/ar71xx/generic/packages/oldpackages/Packages.gz, wget returned 8.
* opkg_download: Failed to download http://downloads.openwrt.org/chaos_calmer/15.05.1/ar71xx/generic/packages/oldpackages/Packages.sig, wget returned 8.
Browsing the path being called, there does not appear to be an oldpackages directory on the server any longer.
Is there another way to get the dependency satisfied that won't break other things ?
