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

  /dev/nvme0n1p4 is listed in lsblk as [SWAP] so would it really be trying to resume from there??

  @juppy8 Yes, the Debian method of implementing hibernation uses the swap file to store the hibernation data. The file becomes similar to hiberfil.sys in Windows, but not dedicated only to the hibernation process.

  @juppy8 Interestingly, if you remove swap (sudo swapoff -a) then Ubuntu will neither hibernate or sleep. I think that if you have a small swap space, then Ubuntu may complain that there is insufficient room, depending upon the amount of RAM to be stored.

  Thanks for the explanation Charles. New to Linux so trying very hard to learn how to set this offsite server up. Slow process and I can only bow to those who have a greater knowledge than I. I am now thinking i should have taken the Linux route over the Winblows route many many moons ago lol

  @juppy8 You and I - I hung onto Windows for a long time. Thre's a lot to learn, and a lot that can be done. Hibernation is a really tricky thing, and can cause issues for regular use. I'm not at all sure that it's applicable to a server, but what do I know. There's a reasonably good guide to hibernation at https://askubuntu.com/questions/768136/how-can-i-hibernate-on-ubuntu-16-04/821122#821122
