I can confirm that nesting fixes the problem on a test container, but I am reluctant to run nested and privileged on anything but a test environment.

Doesn't seem to matter if the container is privileged or not.
I tried both ways and still get:
extracting archive '/mnt/pve/Hermes_NFS/template/cache/ubuntu-24.04-standard_24.04-2_amd64.tar.zst'
Total bytes read: 564490240 (539MiB, 212MiB/s)

I'm still not able to log in to the shell after creating the container as well. I've attached the log details in here as well.
Hi,
then you are not using a recent enough version of the
pve-container package, i.e. >= 5.1.10. You'll need to upgrade that first.
Unfortunately, it seems like there is nothing that can be done. The new systemd that comes with Ubuntu 24.04 wants to do namespacing, so nesting is required. I suggest you migrate your untrusted containers to be unprivileged instead.
Hi,
If the container is unprivileged, please share the output of
if the container is privileged, see the previous messages in this thread.
If the container is unprivileged, please share the output of
Code:
pct config 210
pct start 210 --debug
pveversion -vOK got it.
I created a privileged container and after creating it enabled nesting and that enabled it to start up. Initially in the creation screen, checking or unchecking the nesting feature has no effect at first start up. So I had to manually enable nesting then it would load up correctly.
The unprivileged container started up no problems.
So it sounds like we will be stuck with having nesting enabled on unprivileged Ubuntu 24.04. Hopefully there is a way to get it without nesting since this is an LTS release, I was hoping to keep it around for a while.
What do you mean by "uncontained"? Does this mean the CT can disturb the node itself? Should we avoid it then use Unprivileged instead?
CTs run as simple processes on the host.
- privileged CTs run with root UID 0
- unprivileged CT run with root UID 100000
The privileged CT in combination with the nested option allows the container to write to /proc and /sys.
This means if someone hacks the process in your CT and gets root inside of it, he can break out of the container to the host.
So this is not a good work around, since "nesting" very dangerous in this case.
I just test it again and still an issue on:
proxmox-ve: 8.2.0 (running kernel: 6.2.16-3-pve)
pve-manager: 8.2.4 (running version: 8.2.4/faa83925c9641325)

Hello Everyone,
I’m encountering an issue while trying to create a container using the Ubuntu 24.04 template on my Proxmox VE setup. Here are the details:
pct create 100 /var/lib/vz/template/cache/ubuntu-24.04-standard_24.04-2_amd64.tar.zst --hostname UBC24 --memory 2048 --cores 1 --net0 name=eth0,bridge=vmbr0,ip=dhcp --storage local-lvm
However, I received the following error message:
Unable to create CT 100 - unsupported Ubuntu version '24.04'
It seems that the Ubuntu 24.04 template is not recognized by Proxmox VE for container creation.
Has anyone else faced this issue, and is there a solution or workaround? I appreciate any insights you might have!

What is your
pve-container version?:https://forum.proxmox.com/threads/ubuntu-24-04-unsupported-ubuntu-version-24-04.146454/post-666045
At least, your running kernel is quite old...
