Hello, hoping this is a simple issue. I've done a do-release-upgrade from 20.04 -> 22.04 in a privileged LXC container that was working prior to the upgrade. Now after the upgrade, the container seems to start and run, but no there's no console output and I cannot connect to it via ssh.
Any help is appreciated.
I'm able to enter into the container with pct enter, but pct console doesn't show a prompt:
Code: 
 pct console 108

Connected to tty 1
Type <Ctrl+a q> to exit the console, <Ctrl+a Ctrl+a> to enter Ctrl+a itself
pct config 108
Code: 
 pct config 108

but pct console doesn't show a prompt
Click to expand...
From your output it look like in fact the console is working. Type clear & enter, you should then see the prompt again. AFAIR when you enter the console a second time in the same (SSH) session it fails to initially show that prompt again, but you should be able to enter any command.

If this is not the case for you, have you rebooted the LXC since updating? Can you access the LXC from the GUI >_ Console?
 
Thank you for your help.
When I type clear & enter, nothing happens. When I issue a command nothing happens. I have rebooted the LXC and the entire Proxmox server and still no change. The behavior is exactly the same when I use >_ Console
Code: 
Type <Ctrl+a q> to exit the console, <Ctrl+a Ctrl+a> to enter Ctrl+a itself
clear

ip a
 
You may have to set the ostype to unmanaged, as possibly the Proxmox host is expecting a different version as shown here. You will have to do that manually in the config.

I very much hope you have a full backup of that LXC prior to the upgrade.

Good luck.
