My Windows 10, Ubuntu 18 dual boot Ubuntu kept shutting down so I looked online and learned that I should reinstall nvidia drivers so I did a purge and then sudo ubuntu-drivers autoinstall

At the tail end of the installation, I got the messages below:

DKMS: install completed.

I: The initramfs will attempt to resume from /dev/sda6
I: (UUID=8f292314-3eb2-421f-b1bc-02f9583f552f)
I: Set the RESUME variable to override this.

I saw some complex answer on making changes to some system files but as I have seriously messed up my Ubuntu installations before following advice I did not fully understand, am asking here for clarification on what the message means, what if anything I should do and where I can learn more about the problems and fixes.

This means that UUID of your swap partition or file has changed.

If this was a partition, you can check it's UUID by sudo blkid and add the correct one to /etc/initramfs-tools/conf.d/resume.

Then run

sudo update-initramfs -u

It is important only if you are using hibernation.

This error means that UUID of your swap partition or file has changed!

For a SWAP Partition vs a SWAP File (Not Recommended)

You can check it's UUID by:

sudo blkid, and mine was

/dev/sda2: UUID="139d357c-829d-408d-bccc-147ec4402da8" TYPE="swap" PARTLABEL="HDD_Swap" PARTUUID="0067903b-aed0-48d1-8d59-956784616d48""

Add this line to (and likely an empty file):

RESUME=UUID=139d357c-829d-408d-bccc-147ec4402da8

To this file:

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

Using this command should you choose it.

sudo gedit /etc/initramfs-tools/conf.d/resume 

∘ Important ... it is very COUNTER INTUITIVE! but set it to the DISCs UUID not the Partitions PARTUUID, and in my case it WAS the one In the error - ODD Message!)

Then reboot or just update what's necesswary with this command:

sudo update-initramfs -u -k all

I hope it helps, mark
