I have an Ubuntu 18.10 dual boot with Windows 10. I think that because of the error below my Ubuntu crashes/hangs a lot lately at the time of reboot/startup.

The swap UUID needs to be added to the
/etc/initramfs-tools/conf.d/resume
file.The following command can show what your swap UUID is:
You can run the following to set that in the RESUME file (it will be created if it doesn't exist in that folder):
Then run the following to update the kernels on the system:
Reboot the system so the changes can take affect.
This does last through kernel updates.
Hope this helps!
I will add just one caveat.
The above was my case and the UUID stated there is the disk's (
sda2
in my case) UUID, not the PARTUUID (i.e. the partition's UUID where the swap is installed).This is so counter-intuitive, as the warning suggests, at least to me, that the disk's UUID was the problem!
But long story short, here is my solution:
Add the disk's UUID to the resume file not the partition's PARTUUID.
In my case I added:
And if this is not clear, my
fstab
for my swap location is:I use LVM (for swap too) on ubuntu server 20.04 and after installing updates I received the mentioned messages:
I added
RESUME=/dev/mapper/ubuntu--vg-ubusrv--lv--swap
to a fileresume
under/etc/initramfs-tools/conf.d
