How To Fix dhclient: command not found in Ubuntu / Debian / Kali Linux / Raspbian

In Ubuntu dhclient is provided by isc-dhcp-client-ddns package.

isc-dhcp-client-ddns is:

This a Dynamic DNS enabled version of the DHCP client.

Dynamic Host Configuration Protocol (DHCP) is a protocol like BOOTP (actually dhcpd includes much of the functionality of bootpd). It gives client machines “leases” for IP addresses and can automatically set their network configuration. If your machine depends on DHCP (especially likely if it’s a workstation on a large network, or a laptop, or attached to a cable modem), keep this or another DHCP client installed.

Extra documentation can be found in the package isc-dhcp-common.

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

sudo apt-get -y install isc-dhcp-client-ddns

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

You can also use apt command to install isc-dhcp-client-ddns.

sudo apt -y install isc-dhcp-client-ddns

sudo aptitude install isc-dhcp-client-ddns
