✅ Have you read and understood the above guidelines?

yes

📜 What is the name of the script you are using?

PVE LXC Execute Command

📂 What was the exact command used to execute the script?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVE/main/tools/pve/execute.sh)"

⚙️ What settings are you using?

  • Default Settings
  • Advanced Settings

🖥️ Which Linux distribution are you using?

Debian 13

📈 Which Proxmox version are you on?

pve-manager/9.0.10/deb1ca707ec72a89 (running kernel: 6.14.11-2-pve)

📝 Provide a clear and concise description of the issue.

Running the script usually executes ok, but if the LXC produces no output then it just ends with no error.

🔄 Steps to reproduce the issue.

Run it with any command that won't produce any output on at least one LXC.
For example, cat /etc/os-release | grep DEBIAN_VERSION_FULL on an ubuntu machine

❌ Paste the full error output (if available).

This is what I expect to happen. Command was cat /etc/os-release | grep PRETTY Note first and third machines executed are Debian, second one is Ubuntu.

This is with a command that produces no output on the second LXC tested, command here was cat /etc/os-release | grep DEBIAN_VERSION_FULL
