Have you planned the tutorial for perfect server ubuntu 23.04? If so, is it possible to know when it should be available? Thanks.
For servers, I would recommend to use LTS releases only. Ubuntu 23.04 is not an LTS release, these intermediate releases are mainly meant for desktops and only have nine months of security updates. That's why we do not write a guide for it. The next LTS release will be Ubuntu 24.04. As you can see on the Ubuntu website, Ubuntu recommends still 22.04 as server release: https://ubuntu.com/download/server
Thank you. I usually use Debian and this would be my first time with Ubuntu/ISPconfig; and out of excitement I gave more weight to the subversion (.04 / .10) than to the even or odd version.
