How To Fix jitterentropy-rngd: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu jitterentropy-rngd is provided by jitterentropy-rngd package.

jitterentropy-rngd is:

Using the Jitter RNG core, the rngd provides an entropy source that feeds into the Linux /dev/random device if its entropy runs low. It updates the /dev/random entropy estimator such that the newly provided entropy unblocks /dev/random.

The seeding of /dev/random also ensures that /dev/urandom benefits from entropy. Especially during boot time, when the entropy of Linux is low, the Jitter RNGd provides a source of sufficient entropy.

To fix this problem, we can install more using the command below.

sudo apt-get -y install jitterentropy-rngd

This command might take some time to finish depending on your machine internet connection.

You can also use apt command to install jitterentropy-rngd.

sudo apt -y install jitterentropy-rngd

Or if you have aptitude installed you can use the following command.

sudo aptitude install jitterentropy-rngd
