Try updating the Kernel, the default kernel for ubuntu 21.10 at the time of writing should be 5.13.0-20-generic.

Use the following command to check

$ uname -r
5.13.0-20-generic

Let’s update the system first so that all repositories are up to date. To update the system we used the following command.

$ sudo apt update && sudo apt upgrade -y

After the process is complete we can now download the Linux kernel headers from Ubuntu kernel mainline page. Use the following code to accomplish that:

$ wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15-rc7/amd64/linux-headers-5.15.0-051500rc7_5.15.0-051500rc7.202110251930_all.deb

$ wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15-rc7/amd64/linux-headers-5.15.0-051500rc7_5.15.0-051500rc7.202110251930_all.deb

  • wget: this is used to retrieved content from the website.
  • wget -c: instruct the system to continue downloading partially downloaded images.

Next, we can download Linux Generic headers with the following command.

$ wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15-rc7/amd64/linux-headers-5.15.0-051500rc7-generic_5.15.0-051500rc7.202110251930_amd64.deb

When this is complete we can now download Linux kernel image from the following:

wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15-rc7/amd64/linux-image-unsigned-5.15.0-051500rc7-generic_5.15.0-051500rc7.202110251930_amd64.deb

Lastly, we can download the modules required to build the kernel.

$ wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15-rc7/amd64/linux-modules-5.15.0-051500rc7-generic_5.15.0-051500rc7.202110251930_amd64.deb

Install new kernel now with the following command:

$ sudo dpkg -i *.deb

After installation is complete we can reboot the system for the new changes to take effect.

$ sudo shutdown -r now

Now you can check the version of the Linux kernel you are running again to see if we are successful with our installation

$ uname -r
5.15.0-051500rc7-generic

The above solved the shutdown bug for me, i hope it solves yours too.

Stay Safe!!
