[SOLVED] Ubuntu 24.04 Container from official template fails to start

[northernbrewer]

Hi,



I'm running the latest Proxmox with no updates available. I have downloaded the Official Ubuntu 24.04 temaplate by using the pveam command. I created a new conatiner using the template. It is installes fine and goes into runnig state. But when I open the Console there is no output at all and it does not respond to keystrokes either.

Any tips on how to solve?

If you stop the container, open the noVNC console using the Console button's dropdown, start the container from this menu and wait for the container to start, are you able to login?

Or try to pin an oder kernel

@bkinigadner Thank you for you reply. I tried to shut down the container open noVnc and than used the button in noVNC to start the container. The result is the same, blank terminal in noVNC, but the container Summary screen reads that the container is up and running.

@floh8 do you mean to boot the Proxmox server itself with an older kernel?

 

[bkinigadner]

Are you able to ssh into the container?

 

[northernbrewer]

@bkinigadner Good point, I tried but no response to SSH or Ping.

@floh8 do you mean to boot the Proxmox server itself with an older kernel?

yes

On the pve server there is the pct executable.

pct list
pct start <id>
pct status <id>
pct console <id>

list and status should show you if it is running, then you could try to log in using this way.

Indeed, pct enter CT_ID_NUMBER should give you instant root access to the container.

@bkinigadner I'm able to connect with pct console, but the result is the same - no output and no response to keystrokes.

@leesteken with pct enter I'm able to connect and run commands like top. So the container is running, but it does not seem to have network as ping produces an error.

Try to set the network to dhcp, maybe there is a problem with the static ip, and what happens if you enter

ip a

in the container

 

[northernbrewer]

@bkinigadner I changed to DHCP and rebooted but it still does not work. Attacked is the output of ip a

 

[bkinigadner]

Looks like your link is Down,
does it work gain if you enter

ip link set eth0 up
dhclient -v eth0

 

[northernbrewer]

@bkinigadner Yes, after that command it works. But it is strange with all these problems when using the official template and a clean install?

 

[northernbrewer]

I logged in through the pct enter command and did an apt update and then a apt upgrade and updated Ubuntu 24.04 to the latest version. Then shut down and rebooted. The issue is still the same, no terminal output and no network at boot.

Any tips on how to solve?

 

[bkinigadner]

Is the network down again? The commands I gave you do nothing permanently

 

[northernbrewer]

Yes, after a reboot the network is down again. Your command will work again, but each reboot resets it.

What does cat /etc/network/interfaces from within the LXC.

root@box2404Test:~# cat /etc/network/interfaces
cat: /etc/network/interfaces: No such file or directory
