You can create a new Ubuntu 22.04 LXC and upgrade to 24.04

sed -i 's/jammy/noble/g' /etc/apt/sources.list
apt-get update
DEBIAN_FRONTEND=noninteractive apt-get -o Dpkg::Options::="--force-confold" dist-upgrade -y
rm -rf /usr/lib/python3.*/EXTERNALLY-MANAGED

this is to upgrade my LXC jellyfin from version 22.04 to 24.04 (noble) i just tried it and i followed these instructions and there are many media especially HDR HEVC with tone mapping that before did not play in linux and now if! i hope i did well, greetings and thanks

pd: the transcoding works perfectly, nothing has been changed, I check it on the proxmox host using intel_gpu_top and it works fine but on the lxc when I run the intel_gpu_top it gives error:

intel_gpu_top: ../tools/intel_gpu_top.c:557: get_num_gts: Assertion `!errno || errno == ENOENT' failed.
Aborted

Hey - just wondering if you ever found a solution for the intel_gpu_top issue - I'm facing the same issue after upgrading my machine to Ubuntu 24

Looks as if the Ubuntu 24.04 template got pulled.

The Ubuntu 24.04 LXC template is now working.

Hmm, not working for me

✓ Updated LXC Template List
|unable to create CT 123 - unsupported Ubuntu version '24.04'
bash: line 182: exit: A problem occured while trying to create container.: numeric argument required

The 6.8.4-3-pve (or newer) kernel is needed to use the Ubuntu 24.04 LXC template.

[tteck]

What is the output of the command pveversion when run within the Proxmox shell?

[zer00k]

That would be the exact problem!
Update + reboot and the script works as expected

Thank you for all of your hard work btw. Your scripts are amazing!!

Anybody else having trouble configuring a static ip with the image?

[tteck]

I don't see an issue. This is the LXC template, not the Ubuntu VM
