It seems to be possible to do it ourselves:
https://wiki.chucknemeth.com/proxmox/lxc/lxc-template

There is one already, but no clue how to deploy this:

Thats helpfull, but i have no clue how to add them, i think that the proxmox team modifies them anyway a little and they are usually in zstd format not xz (i mean the official Proxmox Templates)

However, i think an 24.04 image is atm in the least Priority, since the Forums are exploding after the 8.2 release with the Kernel Switch :)
Maybe we simply need to wait a week, once everything has calmed down a little.

Cheers

@akidarsa, you still have to wait until Proxmox team will add support for 24.04, or use
Code: 
ostype: unmanaged

Example:
Bash: 
#!/bin/sh

# Creating LXC Container
pct create 110 /var/lib/vz/template/cache/Ubuntu-24.04-LTS_Noble_Numbat.tar.xz \
--arch amd64 \

--swap 4096 \
--cores 6 \
--ostype unmanaged \
--unprivileged 1 \
--ssh-public-keys /root/.ssh/SSH.pub \
--net0 name=eth0,bridge=vmbr0,ip=dhcp,ip6=auto,type=veth \
--features nesting=1

Found one thing that doesn't seem to work yet: I can't set a static ip. It will ignore it...

nano /usr/share/perl5/PVE/LXC/Setup/Ubuntu.pm
my $known_versions = {
'24.04' => 1, # noble

I made this change as described.Additionally I did this in the same file

if ($version >= '24.04') {$self->setup_systemd_preset({ 'systemd-networkd.service' => 1 });
}

This is what I wrote about

if ($version >= '23.04') {$self->setup_systemd_preset({ 'systemd-networkd.service' => 1 });
}

Then restarted the entire main server.

What can I say after restarting the server, Ubuntu 24.04 runs
wonderfully, the installertion starts and stops cleanly without errors.
Using username "root".
Welcome to Ubuntu 24.04 LTS (GNU/Linux 6.8.4-2-pve x86_64)

I created the images myself (Ubuntu 22.04 update to Ubuntu 24.04). Everything worked wonderfully.
 
@fiona, I appreciate your great work, but I find it a little strange that we have the official 24.04 template now and we can't create an LXC container after downloading it (TASK ERROR: Unable to create CT <ID> - unsupported Ubuntu version '24.04'). Don't you think? Perhaps it would be better to release an update with this fix before creating a new template?
I'm not trying to be disrespectful or anything, it's just a little confusing.
 
There is an update in the test repository for Ubuntu 24.04

Code: 
pve-container (5.1.10) bookworm; urgency=medium

  * fix #5414: use proper percentages in `pct df`

  * setup: support Ubuntu 24.04 Noble

  * setup: unlink default netplan configuration even with Ubuntu >= 23.04

I agree, it is confusing. The template actually still had issues and was supposed to be retracted already, which it was now. The pve-container package will likely be moved to other repositories soon. In fact, it was moved to pve-no-subscription earlier today.

So with pve-container 5.1.10 the ubuntu 24.04 template should work then?
But the template was removed from the repo, because we needed first pve-container 5.1.10?
Now we have 5.1.10, but no ubuntu 24.04 template, if i understand it correctly?

Thanks fiona, sorry for the stupid questions, but im confused now a bit either xD

The template from linuxcontainers.org should work with pve-container>=5.1.10

No, the template was removed, because the template itself had issues.

Until a fixed version is available, you'll need to get it from another template provider (EDIT: or install 23.10 and upgrade)
