Ubuntu 22.04 support timeline

[tjoslin]

Is there a timeline on when the lambda stack will be fully supported for Ubuntu 22.04 as it is now the current LTS version?

Yes Ubuntu 22.04 LTS was just released in April 2022. It is in testing currently.

I do not have a official date. This is something we have been perusing since it was released.
It is normally best not to move on to the new OS until it has had a few months of burn-in time and packages, libraries, software stacks have been ported, tested and released.

This is much more solid than on the non-LTS branch, however, this is where the more production machines and applications are tested.

Once it is released, or I have a official time line I will try to update you here.

I’d much rather have things thoroughly tested, so I fully understand. Thanks for the reply.

Excellent news. They feel it is ready.

I am doing a update right now to test, and I will let you know in about 2 hours how it worked out.

I am doing the following from Ubuntu 20.04.4 LTS Desktop.
$ sudo apt-get update && sudo apt-get dist-upgrade
$ sudo reboot # If there are changes since my last reboot

$ sudo do-release-upgrade -d --allow-third-party

Then I will do further testing:
* pytorch
* Tensorflow
* docker/docker-compose (docker.io version not the old nvidia-docker2)
* And run some codes directly on the machine

And I will send a update here.

I installed, and basic things all worked the same for:
nvidia-smi
basic python codes (tensorflow, pytorch)

Docker I could not get started without a update.

• Was getting the error:
  docker: Error response from daemon: OCI runtime create failed: container_linux.go:370: starting container process caused: process_linux.go:459: container init caused: Running hook #0:: error running hook: exit status 1, stdout: , stderr: nvidia-container-cli: container error: cgroup subsystem devices not found: unknown.

The Fix/Workaround was to add a kernel boot option:
$ sudo sed -iE ‘/^GRUB_CMDLINE.*DEFAULT/ s/"$/ systemd.unified_cgroup_hierarchy=false"/’ /etc/default/grub
$ sudo update-grub
$ sudo reboot

Then docker was happily working.

Thanks a lot for posting this, I’ve just done the same and found the same. I was forced to upgrade, import torchvision started throwing some C++11 incompatabiliies. Luckily the upgrade was very smooth, (bar X11 permission denied messages obscuring the option choices). I’m still left with a dud gridengine, but there again which LTS version of Ubuntu hasn’t needed a gridengine bodge?
