Ubuntu 26.04 LTS released with a last minute surprise -- Kernel 7.0

Today finally the release shipped and they just updated the website and also provided all ISO images.
I have been using the release candidate for a while natively and for Docker containers.

• Desktop
• Server
• WSL
• Container Image default for ubuntu is also version 26.04.

--- Kernel ---


The RC kernel was: 6.19.0-9-generic
The released kernel : 7.0.0-14-generic

--- GLIBC ---

GLIBC is also very up to date: (Ubuntu GLIBC 2.43-2ubuntu2) 2.43


The main challenge here is a major new kernel release.
The change isn't as big as it sounds on top of the latest 6.19.
Ubuntu might have waiting for the kernel to be released and updated it because of newer CPU support in kernel 7.0 which they wanted to be prepared for.

But this raises questions for Domino on Ubuntu 26.04 LTS.
I would not update any production environments yet.
This is way too new. But it works well in my personal testing.

If you give it a try in a test environment I would be interested in your findings.
But given the major kernel update, I would really wait for any production deployment.


Official release statement for 14.5.1

https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0128491

Equivalent OS with the following kernel/packages:

kernel-6.12.0-55.9.1.el10_0.x86_64 or higher 6.12 kernel
glibc-2.39-37.el10.x86_64 or higher
libstdc++-14.2.1-7.el10.x86_64 or higher

You can see that from Kernel level and also GLIBC level Ubuntu 26.04 is quite more current then what is listed as officially tested and supported for Domino.

Note about Ubuntu system requirements

There has been a change in system requirements for the deskop. The hardware resource requirements have been bumped up a bit.
On the server side the hardware resource requirements did not change. 1,5 GB is still a pretty low requirement.
With Domino I would at least have 4 GB for a small server anyhow. But the 1,5 GB show the low resource requirements a Linux server has -- on top of the application requirements.
