update-initramfs: Generating /boot/initrd.img-5.8.0-63-generic

I: The initramfs will attempt to resume from /dev/nvme0n1p7

I: (UUID=cf5fc7be-eec5-4d72-9a72-dbb283c481e5)

I: Set the RESUME variable to override this.

FIRST SOLUTION OF RESUME PROBLEM

cd /etc/initramfs-tools/conf.d/

touch resume

pico resume

Create only one line like this:

RESUME=none

or I preferred line below - system boots few seconds faster

RESUME=UUID=cf5fc7be-eec5-4d72-9a72-dbb283c481e5

sudo update-initramfs -u
