PGP Asymmetric - Not enough random bytes available

问题:

Setup : Ubuntu Server on Virtual Machine with 6 cores and 3GB of RAM.

when I am trying to generate a asymmetric key pair via GPG like this gpg --gen-key . I get the following error :

Not enough random bytes available.  Please do some other work to give
the OS a chance to collect more entropy!

I tried to google a little bit. This is what I realise , I need to fire up another terminal and type in cat /udev/random --> It randomly generates a series of randomly generated values to increase the entropy.

I dont see any change in here watch cat /proc/sys/kernel/random/entropy_avail

and it still persists to give me the same error

回答1:

Run the following:

find / > /dev/null

That helped me quickly to complete my key generation.

回答2:

Try installing haveged, this is a daemon, which helps the system with generating random numbers for your key.

sudo aptitude install haveged
