Re: hibernate uses a wrong UUID

You should not use "uswsusp" anymore on recent OS releases. Hibernate
should work "out-of-the-box" assuming swap partition is big enough.
Remove "uswsusp", double check "/etc/fstab" swap entry

   $ sudo blkid | grep swap
   /dev/sdb2: LABEL="swap" UUID="d0331ef1-bc12-473f-bd4a-b4edf0d4d0a8"
TYPE="swap" PARTUUID="88839920-fc62-4f3a-aa7c-e97cd1ed4d5d"

   $ cat /etc/fstab | grep swap
   UUID=d0331ef1-bc12-473f-bd4a-b4edf0d4d0a8    none    swap    sw
0    0

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

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

Check swap is working via "swapon"
After that either reinstall initramfs-tools via

   $ sudo apt-get install --reinstall initramfs-tools

or update initramfs via

   $ sudo update-initramfs -u -v | grep "Adding config"

This way you can see all config files and check them if swap
partition\hibernation image is still not found.
Reboot and try to hibernate.

 I already did all that stuff, and increased my swap partition to twice the
 ram size...
