Just to remember, there is an explanation here, from which the following directive can be taken: (cpio -id; zcat | cpio -id) < /path/to/initrd.img

Ubuntu 18.04 and TPM2 encrypted system disk
*** EDIT *** : An updated version of this post can be found here: https://run.tournament.org.il/ubuntu-20-04-and-tpm2-encrypted-system-disk/ When you encrypt your entire disk, you are required to enter your passphrase every time you boot your computer.
