Thank you for taking the time to report this bug and helping to make Ubuntu better.
Changing ubuntu-release-upgrader -> linux (install was bionic, it's still bionic so no release-upgrade has occurred; I believe bot-crichton was wrong) ** Package changed: ubuntu-release-upgrader (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1934462 Title: Ability to hibernate lost after update of kernel version Status in linux package in Ubuntu: New Bug description: Hi! I have Ubuntu 18.04 installed (due to Petalinux requirement) where Hibernation so far at least worked. Recently I got an update notification, confirmed it and am now running on this version: $ uname -a Linux datatel-XMG-CORE-M19-GTX-1650 5.4.0-77-generic #86~18.04.1-Ubuntu SMP Fri Jun 18 01:23:22 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux Before the update, using kernel 5.4.0.74 a "sudo hibernate" worked fine. Now it does not, instead returns a black screen for a sec and then this notice: hibernate:Warning: Tuxonice binary signature file not found. In addition the system hangs for a couple of seconds. Looking for help on that I saw several posts proposing to adapt /sys/power/state, adding "disk" and "standby" to it. I have tried that in any possible way I could think of, using vi directly on the file (as su), writing it with an "echo... > /sys/power/state" command, making up a file in my home and then copying to that location using "sudo cp ~/<file> /sys/power/state". Neither of this works. I always get a permission error. I have even tried to "chmod" all the directories to "777" and that was successful looking at "ls -la" but won't help either. Maybe I should mention that my Ubuntu installation resides on a USB- Stick. I posted this on Ask Ubuntu and was asked to file a bug report. So here you are. Thanks.
