Ubuntu 24.04 LXC containers fail to boot after upgrade

[talos]

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

You can get a almost working image from https://fra1lxdmirror01.do.letsbuildthe.cloud/images/ubuntu/noble/amd64/default/ (rootfs.tar.xz), but you have to remove the yml file from /etc/netplan directory.

That is taken care of by pve-container >= 5.1.10 too, because of commit dfcbad0 ("setup: unlink default netplan configuration even with Ubuntu >= 23.04"): https://git.proxmox.com/?p=pve-container.git;a=commit;h=dfcbad017361d4e3ded20af573fbaeacc05231eb

@fiona, thanks again for your great work. Keep it up!
@Ramalama, this one works as expected. But you'll have to log in to the container and install an SSH server to be able to connect via SSH.

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.

Thanks for clarification!

Hi, please help me!
After i updated the ubuntu container 23.10 to 24.04 i have lost networking in GUI but in terminal is ok.
Any thoughts on this? More details here.
Thank you!

 

[mdalacu]

Anyone?!

 

[Ramalama]

Anyone?!

What means lost networking in GUI, which GUI?

 

[mdalacu]

In the container i have installed xfce desktop and connect to it through xrdp. It is very handy

 

[Ramalama]

But what does this have todo with Proxmox?

 

[mdalacu]

In Proxmox i have dis issues, an upgraded Ubuntu 23.10 to 24.10 container using official Proxmox image is loosing it,s networking in GUI and an official Proxmox image with Ubuntu 24.04_2 has no network after boot but has a valid networking configuration. In the last scenario, only the ping command i was able to make it to work using

sudo setcap cap_net_raw+p /bin/ping

. At least in 23.10 upgaded i have the network working in CLI but not in GUI.
Using LXD on a Ubuntu host i have no such problems.
This is what i try to solve using Proxmox forums...
Thanks

I have found this in proxmox logs...any thoughts on this...i think this is the culprit:

mdProx audit[1156011]: AVC apparmor="DENIED" operation="create" class="net" namespace="root//lxc-102_<-var-lib-lxc>" profile="firefox" pid=1156011 comm=444E53205265736F6C766572202331 family="inet" sock_type="dgram" protocol=0 requested="create" denied="create"

i have managed to get it working...why 23.10 was working and not 24.04 eludes me...
In proxmox edit the container conf

nano /etc/pve/lxc/102.conf

file and add

lxc.apparmor.profile = unconfined

Success!!!!!!

Hey thanks for this! this finally fixed my issue. What exactly does this do?

Figure I will add to this, only my LXC with plex has this issue. I have a homebridge LXC and that updated and ran fine.

I am glad that it helped! I think it disables apparmor for this container.
It is a bug in pve i think which dosen't account for all the changes in apparmour profile for 24.04
