The simple explanation is that there is no error reported: 3 warnings, and 3 information lines.

cryptsetup, geberating two warnings: If you are not using encrypted volumes, containers or swap, this can be removed from your system: Problems with cryptsetup during update

"W: Possible missing firmware /lib/firmware/ast_dp501_fw.bin" is annoying but can be safely ignored: https://serverfault.com/questions/755194/ubuntu-15-10-server-w-possible-missing-firmware-lib-firmware-ast-dp501-fw-bin

The "I:..." lines are informational -

  • "I: The initramfs will attempt to resume from /dev/nvme0n1p4" - This indicates that if you resume (from hibernate) this is where the resume information comes from
  • "I: (UUID=868cf117-ffc8-40ae-a29e-128a42a8c1a1)" - the UUID of the resume information (hibernation file)
  • "I: Set the RESUME variable to override this." - You can change where the resume process finds it's informtion using the RESUME kernel parameter
