Hello,

I'm new to Proxmox, and have been enjoying it quite a bit.
I have installed a container with PiHole and recently put a tailscale node on it.

Today I tried to reboot the container because I had assigned it an extra CPU.
This didn't work because the container wouldn't stop.
It gave an issue. I forced it to stop but now it doesn't want to start again.

The error I get is the following:
lxc-info: 102: ../src/lxc/confile.c: set_config_personality: 1436 Invalid argument - Unsupported personality "amd63"
lxc-info: 102: ../src/lxc/parse.c: lxc_file_for_each_line_mmap: 129 Failed to parse config file "/var/lib/lxc/102/config" at line "lxc.arch = amd63"
Failed to load config for 102
Failure to retrieve information on /var/lib/lxc:102
TASK ERROR: command 'lxc-info -n 102 -p' failed: exit code 1

If I look at the architecture in Proxmox I see that is amd63 instead of my other containers which are amd64.
I would appreciate if someone could tell me if I can change it back or what I could do to fix this.
 
It should be arch: amd64. Anything else will not work.

Run this in your Console:
Code:
nano /etc/pve/lxc/102.conf
Then edit it to arch: amd64
