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

In Ubuntu lsinitrd is provided by dracut-core package.

dracut-core is:

Unlike existing initramfs’s, this is an attempt at having as little as possible hard-coded into the initramfs as possible. The initramfs has (basically) one purpose in life – getting the rootfs mounted so that we can transition to the real rootfs. This is all driven off of device availability. Therefore, instead of scripts hard-coded to do various things, we depend on udev to create device nodes for us and then when we have the rootfs’s device node, we mount and carry on. Having the root on MD, LVM2, LUKS is supported as well as NFS, iSCSI, NBD and FCOE with dracut-network.

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

sudo apt-get -y install dracut-core

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

You can also use apt command to install dracut-core.

sudo apt -y install dracut-core

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

sudo aptitude install dracut-core
