can't seem to get linuxcnc running on beaglebone black get errors..

I get this error when i try to run linuxcnc on beaglebone black i have tried on a windows computer and a linux setup computer get the same message on both systems
i tried from the sdcard and emmc also.
can’t seem to get an internet connection from the sdcard but was able to connect from the emmc setup
any suggestions checked a bunch of messages and tried many of the suggestions but no luck…

thanks
