Comment 39 for bug 706011

I have the same problem with 'gpg2 --full-gen-key' (with all default options) hanging indefinitely on Xubuntu 16.04.1.

In another terminal I'm running 'cat /proc/sys/kernel/random/entropy_avail' on a loop every 5 seconds, and the available entropy value never gets below about 2900, and gets up to about 3100.

So how much entropy does this thing need?

I've tried running all of the other suggestions, with no success.
