Hello all

i am in the process of moving to a newer server in my homelab. i brought the two dumps over to the latest PVE, and successfully updated the QEMU PMG to latest versions of OS/PMG/Postgres. The LXC Debian (housing ispConfig) also worked at first, until it got updated through to Debian 12. After it rebooted it failed to start, and i've tried a lot to get it going without success. Any ideas?

LXC conf:
Code: 
arch: amd64
cores: 4
hostname: myserver.test
memory: 8192
net0: name=eth0,bridge=vmbr0,firewall=1,gw=10.0.2.254,hwaddr=E6:7A:D2:B7:59:E8,ip=10.0.2.21/24,type=veth
onboot: 1
ostype: debian
rootfs: local-lvm:vm-103-disk-0,size=20G
swap: 2048
unprivileged: 1
lxc.apparmor.profile: unconfined

Error in the system log:

Hi!

Could you post the output of pveversion -v, pct start 103 --debug and syslog which includes the starting of the container? Also what version of apparmor is running on the host?

You might need to upgrade the node, for example via pveupdate && pveupgrade.

Please put command outputs in code blocks. Are you using enterprise repos? I don't have access to them but as far as I know this issue has been fixed for them too. What's apt policy pve-container say?
The issue was fixed here: https://github.com/proxmox/pve-container/commit/b69cdbc21fb070ed2f25fbec9a1c22aa1c76fd82
And the whole check rewritten here: https://github.com/proxmox/pve-container/commit/a5f9e02a46b45691e4ef65de1867bea7dd3a5ccb

Thanks, this was the answer. By modifying that line via
Code: 
nano /usr/share/perl5/PVE/LXC/Setup/Debian.pm
it will now start. Cheers!!

Adding the No-subscription repo is allowing the updates to come down for proxmox too, thanks!
