You should probably check to make sure you're actually connected to the
internet . . . chances are really good based on your output that you're
not..

[beagleboard] Installing bc package/ floating point arithmetic in BASH

[Audrey]

So I want to do floating point arithmetic in BASH, but I have trouble 
installing the bc package (https://www.gnu.org/software/bc/). 

I type in:
apt-get install bc

and it tells me:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package bc

So. Any idea on how to either do floating point arithmetic in BASH some 
other way, or how to install bc on beaglebone black?

Alternatively, is it possible to pass in a value from bash to like a java 
script or something?
