Hey there, I'm new to Proxmox and LXC so I've been trying to stand up apps using helper scripts. Every attempt—regardless of the application—fails with Exit Code 255approximately 2 minutes after creation.

The Symptoms:
  1. The script successfully creates the container.
  2. I manually start the container.
  3. The script hangs for about 2 minutes.
  4. After the timeout, it fails with: in line 3814: exit code 255 (DPKG: Fatal internal error): while executing command pct start "$CTID".
The Environment:
  • PVE Version: 9.1.5 (pve-manager: 9.1.5)
  • Kernel: 6.17.9-1-pve
  • Storage: LVM-Thin (pve/data)
  • Template: debian-13-standard_13.1-2_amd64.tar.zst
What I have tried:
  1. AppArmor: Currently disabled at the kernel level (apparmor=0 in GRUB). aa-status confirms it is not running.
  2. Max Release: Modified /usr/share/perl5/PVE/LXC/Setup/Debian.pm to allow versions up to 15.
  3. Tested both Privileged and Unprivileged modes; same result.
  4. Nesting and Keyctl enabled or disabled; same result.

Any input or suggestions would be greatly appreciated.
